[Follow-up network for newborns at risk for handicap in a French region]. / Réseau de suivi des nouveau-nés à risque de développer un handicap. L'expérience du réseau de suivi régional << grandir ensemble en Pays de la Loire >>.

BACKGROUND AND OBJECTIVES: - Follow-up networks for newborns with a handicap risk need to be put into place downstream of the perinatal health networks. Such a network was implemented in the Pays de la Loire region in 2003. Our objective is to evaluate the feasibility and the capacity to detect infants with an incapacitating condition at nine months corrected age and the patents'satisfaction with such a network. MATERIAL AND METHODS: - A common tool based on the Amiel Tison assessment was set up. Infants included since 1(st) March 2003 and who were two years old corrected age on 1(st) September 2006 were taken into consideration. A satisfaction survey was conducted with the parents of infants showing normal development at two years old corrected age or with an abnormal neuromotor examination. RESULTS: - Amongst the 1339 infants included, 1185 (88.4 %) were seen at the age of two years: 7.3 % showed pathological development, 4.5 % infants showed suspect neuromotor examination. Cares were proposed for 11% of the infants followed, permitting cares from nine months old for 65 % of the infants considered as having a pathological development at the age of two years. DISCUSSION/CONCLUSION: - This follow-up network has fulfilled its initial goal: 2.2 % of newborn babies in the region were included, a low rate of lost for follow-up was observed. Moreover, this network has a relative good capacity for detection and early initiation of care. The application of the parents is important and their level of satisfaction appeared to be high. This experiment shows that regional follow-up networks can become reality, but their efficiency still needs to be improved.

[Monitoring network for vulnerable children in the Pays de la Loire ("Grandir ensemble" - Cohort LIFT): 10 years of activity 2003-2013]. / Réseau de suivi des enfants vulnérables dans les Pays de la Loire (Grandir Ensemble - Cohorte LIFT) : dix ans d'activité de 2003 à 2013.

INTRODUCTION: Vulnerable children are at-risk newborns including premature infants and some children with pathologies presented by fear anomalies and deficiencies, most particularly neurological. Monitoring is based on the detection of these abnormalities and their early management. The organization of this monitoring system is based on a network of doctors, mostly pediatricians, trained regularly. The objective of this review was to assess the resources, means, and results of 10 years of follow-up. METHODS: The Pays de la Loire network includes 24 maternity wards and 13 neonatal departments. Annual admissions are around 5000 newborns to approximately 45,000 annual births. Upon discharge of newborns, born prematurely at 34 weeks of gestation (WG) or less, or term infants with neurological problems, parents are asked to have their child monitored by a referring doctor. During the consultation, a reference document is filled out by the doctor and sent to the project manager for data collection and specific compensation for private practitioners. Standardized questionnaires were used such as the ASQ (Ages and Stage Questionnaire) completed by parents, the developmental quotient (DQ) with the Lézine Brunet-Revised test (BLR), the intelligence quotient (IQ) with the Wechsler Preschool and Primary Scale of Intelligence (WIPPSI III) completed by psychologists employed in the network, and a questionnaire completed by the teacher at 5 years of age. RESULTS: The network started on 1st March 2003, and 28th February 2013, after 10 years of inclusion, 10,800 children had been included. This population accounts for 2.4% of all annual births: 1.1% were included for prematurity less than 33 weeks and 0.25% were term-born infants. The characteristics of children are presented with gestational age, birth weight, and obstetric and neonatal pathologies. The percentage of these children followed was 80% at 2 years and 63% at 5 years. At 2 years, the results are presented according to gestational age with approximately 60% of children without disabilities at 25-26 WG, 73% at 27-28 WG, 77% at 29-30 WG, and 86% at 31-32 WG. Absorptions are diverse and vary according to the age of the child with physical therapy, psychomotor skill work, speech therapy, hearing and vision consultations, and psychology/psychiatry. Assessment tools were refined by specific analyses: the ASQ 24 months (completed by parents) was deemed valid and predictive with respect to IQ (abandoned in 2012), and the grid completed by the teacher was found to predict abnormalities in 5 years. CONCLUSION: The Pays de la Loire monitoring network has met its initial objective, namely to detect disabilities early and provide practical help to parents in a population of vulnerable children. Benefits for professionals and other children not followed in the network were observed, with an increase in pediatricians' skills. The benefits of the evaluation results are more difficult to assess with the care than neonatal care in obstetrics. The sustainability of such a network seems assured for healthcare professionals, provided that funding is maintained by the health authorities.

Newborns are given attentive perinatal care but the organization of further follow-up can be haphazard. The main consequences are the difficulties parents have in finding appropriate medical assistance for caring for high-risk infants and the absence of appropriate surveillance or efficient care. An inpatient-outpatient healthcare network enables early care of these infants and can reduce the consequences of neurosensorial sequelae. The overall impact of the regional perinatal care can also be evaluated. Such a network has been implemented in the Pays de Loire region in France since early 2003. In six months, among 1000 initially included infants, 500 were followed by pediatricians working in an outpatient (40%) or inpatient (60%) setting. This organization enables correction of over-centralization of neonatal care and the absence of coordination for follow up.

H-Ras transfers from B to T cells via tunneling nanotubes.

Lymphocytes form cell-cell connections by various mechanisms, including intercellular networks through actin-supported long-range plasma membrane (PM) extensions, termed tunneling nanotubes (TNTs). In this study, we tested in vitro whether TNTs form between human antigen-presenting B cells and T cells following cell contact and whether they enable the transfer of PM-associated proteins, such as green fluorescent protein (GFP)-tagged H-Ras (GFP-H-Ras). To address this question, we employed advanced techniques, including cell trapping by optical tweezers and live-cell imaging by 4D spinning-disk confocal microscopy. First, we showed that TNTs can form after optically trapped conjugated B and T cells are being pulled apart. Next, we determined by measuring fluorescence recovery after photobleaching that GFP-H-Ras diffuses freely in the membrane of TNTs that form spontaneously between B and T cells during coculturing. Importantly, by 4D time-lapse imaging, we showed that GFP-H-Ras-enriched PM patches accumulate at the junction between TNTs and the T-cell body and subsequently transfer to the T-cell surface. Furthermore, the PM patches adopted by T cells were enriched for another B-cell-derived transmembrane receptor, CD86. As predicted, the capacity of GFP-H-Ras to transfer between B and T cells, during coculturing, was dependent on its normal post-transcriptional lipidation and consequent PM anchorage. In summary, our data indicate that TNTs connecting B and T cells provide a hitherto undescribed route for the transfer of PM patches containing, for example, H-Ras from B to T cells.

Hospital initiation of a vaccinal schedule improves the long-term vaccinal coverage of ex-preterm children.

Preterm infants are experiencing delays in receiving routine schedule vaccines. We evaluated up-to-date immunisation status of 602 preterm infants at 5 and 24 months for DTCoqPolioHib and pneumococcal conjugate vaccine (defined by 3 and 4 doses, respectively). At 5 months, 39% (CI 95% [35-43]) of children were up-to-date for DTCoqPolioHib and 22% (CI 95% [19-26]) for pneumococcal conjugate, while at 24 months 67% (CI 95% [64-71]) were up-to-date for DTCoqPolioHib and 36% (CI 95% [32-40]) for pneumococcal conjugate. After adjustment for gestational age, a primary vaccine before discharge remained linked with a better vaccinal coverage (p<.005, OR=5.0; CI 95% [2.9-8.5]).

[Parent satisfaction with the Loire Infant Follow-up Team (LIFT) premature and at-risk infant network in the Pays-de-la-Loire area (France)]. / Satisfaction des parents dans le réseau de suivi des prématurés et des enfants à risques « Grandir ensemble ¼ des Pays-de-la-Loire.

BACKGROUND: The Loire Infant Follow-up Team (LIFT) is a network for caring for premature infants whose gestational age is 34 WA or less and at-risk neonates in the Pays-de-la-Loire area in France. The network aims to screen for clinical anomalies early and to propose adapted care. Trained physicians follow the included children in a standardized manner at 3, 6, 9, 12, and 18 months and 2 years, with a specific examination by psychologists at 2 years. The aim of the study was to assess the satisfaction of the parents of the children followed. METHODS: To evaluate parent satisfaction, a questionnaire from the Consumer Satisfaction Survey (CSS) in its French version was sent to parents whose infants were 2 years old, stratifying on the presence of an anomaly. The questioner had 39 items, with 8 specific items on the network and 31 from the CSS. The questionnaire was mailed twice in September 2006. RESULTS: Out of 300 questionnaires mailed, 269 were returned (rate 89.7 %). The questionnaire was assessed using principal component analysis with 2 dimensions for the 30 items common to all children, one of which covered empathy with physicians and the other with the consulting psychologists at 2 years. The validity was good (Cronbach coefficient, 0.91). The answers to overall questions such as "We are satisfied with the care in the network" scored 16.1±0.7/20, with 90 % "totally agree" or "moderately agree" responses. The "The care is perfect" scored 14.6±0.7/20 with 78 % agreeing with the statement. The total score for 30 general questions was 14.6±3.1 (median, 14.9). The total score was lower for infants with anomalies: 13.7±3.3 versus 14.9±2.9 (P<0.01). The answers with a low score (<10) were given by 22 parents (8.2 %). There was no significant relation between the total score or the satisfaction score and neonatal events. CONCLUSION: A postal survey is helpful to know the views of parents on the follow-up of their infants. This good level of satisfaction seems to stem from the parents feeling they belong to the network, the quality of the relationships with personnel, and the doctors' empathy, as well as the number of contacts between parents and the network coordinator.
