Purpose: To examine whether the Canadian normative values of the Alberta Infant Motor Scale (AIMS) are appropriate for Dutch infants. Method: In a cross-sectional study, 499 infants developing typically (0.5-19 months) were assessed using the AIMS home video method. The scaling method was used for calculating item locations of the Dutch sample, and Welch test to compare Canadian and Dutch raw scores. Results: The AIMS items (45 of 58) met the criterion for stable regression to calculate item locations of the Dutch data set and compare these with the Canadian data set. Dutch infants passed 42 of 45 items at an older age. Most monthly age groups of Dutch infants had lower mean AIMS scores. Conclusion: The Canadian norms are not appropriate for the Dutch study sample. Dutch infants appear to develop in a similar sequence but at a slower rate. This has implications regarding the clinical use of the AIMS in the Netherlands.

This study examined the effect of meals varying in amount, size, and hardness of food pieces on the development of the chewing capabilities of 8-month-old infants. The study also examined changes in shivering, gagging, coughing, choking, and their ability to eat from a spoon. In an in-home setting two groups were given commercially available infant meals and fruits, purees with either less, smaller and softer or more, larger and harder pieces. Both groups were given these foods for 4 weeks and were monitored several times during this period. After the 4-week exposure period infants in both groups were given the same five test foods. Structured questionnaires with questions on eating behavior and the child's development were conducted 6 times in the 4 to 12-month period and video analyses of feedings were conducted 4 times between 8 and 9 months. After the 4-week exposure period, the group that had been exposed to the foods with more, larger and harder pieces showed a significantly higher rating for chewing a piece of carrot and potato for the first time, but not for a piece of banana nor for mashed foods. Shivering, gagging, coughing, choking, and ability to eat from a spoon were not different between the two groups. These results contribute to the insight that exposure to texture is important for young children to learn how to handle texture. PRACTICAL APPLICATIONS: (a) The study shows the feasibility of testing the effects of texture interventions on chewing capability and oral responses such as gagging, coughing, and choking in infants. (b) The study contributes to the insight that exposure to food texture to learn how to handle texture is important for infants and showed that exposing children to a higher amount of larger pieces improves their chewing capability for a piece of carrot and potato, at least immediately after the intervention.

OBJECTIVE: Coordinating sucking, swallowing and breathing to achieve effective sucking is a complex process and even though sucking is essential for nutrition, little is known about sucking patterns after birth. Our objective was to study sucking patterns in healthy fullterm infants and to describe the age-specific variations.METHOD: We studied the sucking patterns of 30 healthy, fullterm infants longitudinally from 2 or 3 days after birth to 10 weeks of age. During this time we recorded five to seven feeding episodes that we assessed off-line with the Neonatal Oral-Motor Assessment Scale (NOMAS).RESULTS: We found a normal sucking pattern on the second or third day after birth in 27 out of 30 infants. During the following weeks we found abnormal sucking patterns in 23 out of 171 feeding episodes (14%) and normal patterns in 148 episodes (86%). Altogether, between 38 and 50 weeks' postmenstrual age (10 weeks after birth), 10 infants displayed a deviating, arrhythmical sucking pattern. Dysfunctional sucking patterns and problems of coordinating sucking, swallowing and breathing did not occur. Birth weight, gestational age, type of labour and gender did not influence sucking patterns. Arrhythmical sucking was seen more often in bottle-fed infants.CONCLUSION: Our study demonstrated that practically all healthy fullterm infants started off with a normal sucking pattern soon after birth. One-third of the infants displayed one or more deviating episodes up to the age of 10 weeks. Apart from bottle-feeding, no other factors were found that influenced sucking patterns.

Pre-eclampsia (PE) is a common and severe pregnancy complication and is associated with substantial perinatal morbidity and mortality in mothers and infants. The disease is often characterized by a non-specific presentation which makes it challenging for physician to diagnose PE during regular pregnancy check-ups. To date, there are no diagnostic tests on the market for detection of PE early in pregnancy (first trimester). In this project, we will develop a platform to sensitively analyse calcium-binding proteins (CBPs) which will unlock the full potential of CBPs as predictive PE markers. The technology will also be applicable for other diseases (e.g., dementia and cancer) where CBPs are also known to play a key role in disease pathophysiology. We will develop with phage display antibodies that can recognize calcium binding to specific motifs in proteins. To this end we will synthesize peptide motifs with and without calcium to select antibodies that are specific for calcium bound proteins. These antibodies will be validated for their clinical use. For this goal we will use serum samples from the Improved studie (EU subsidised study) to determine if we can recognize pre-eclampsia in a very early stage. This knowledge can lead to a better treatment of pregnant women suffering from this disease and also will probably increase the well-being for the baby born and the development further in life.
Het Godivapp Applied in Pediatric Primary care (GoAPP) project ontwikkelt, onderzoekt en realiseert de implementatie van een e-health applicatie voor uitwisseling van videomateriaal in zelfstandige praktijken (MKB) in de eerstelijnsgezondheidszorg. Voor een goede analyse van bewegingsproblemen bij baby?s uit risicogroepen is het van belang de motorische ontwikkeling te meten en te volgen in de tijd. Kinderfysiotherapeuten gebruiken hiervoor een observatie-instrument, de Alberta Infant Motor Scale (AIMS). In 2014 en 2015 heeft de GODIVA-onderzoeksgroep (GrOss motor Development of Infants using home Video registration with the AIMS) van Hogeschool Utrecht een methode ontworpen, waarbij de ontwikkeling gevolgd kan worden aan de hand van video?s gemaakt door ouders. De methode wordt door professionals gezien als een aanvulling op bestaande methoden, die het monitoring van kinderen doelmatiger en transparanter maakt. De methode past uitstekend in de huidige e-health ontwikkeling en zelfmanagement/empowerment van ouders. Voor research met de videomethode is een prototype applicatie ontwikkeld waarmee op veilige wijze de filmbeelden verstuurd kunnen worden en opgeslagen. Het prototype is nog niet geschikt voor gebruik binnen de beroepspraktijk. Eerstelijns Kinderfysiotherapiepraktijken zouden graag de applicatie gebruiken. Zij verwachten dat het een waardevolle uitbreiding is van hun mogelijkheden en een kans om als praktijk te innoveren. Zij zien, als zelfstandige ondernemers, echter ook belemmeringen, zoals ICT-ondersteuning en een passende tarifering van een videoconsult. Voor deze kleine bedrijven spelen ook betaalbaarheid en gebruiksgemak een essentiële rol. Binnen GoAPP zijn vijf perspectieven voor innovatie en implementatie van e-health bij elkaar gebracht: eindgebruikers, zorginhoudelijk, harde technologie, zachte technologie en bedrijfskundig perspectief. Georganiseerd rondom drie werkpakketten wordt interdisciplinair onderzoek gedaan naar (1) optimalisatie van het videoportal, (2) implementatie, en (3) bedrijfskundige haalbaarheid, via ontwerpgericht onderzoek, literatuuronderzoek, implementatieanalyse en business-case onderzoek. Een vierde werkpakket richt zich op doorgroei van het netwerk kinderfysiotherapeuten naar een Community of Practice. Doel: Een innovatieve videomethode voor het observeren van de motoriek van zuigelingen, geschikt voor eerstelijnspraktijken kinderfysiotherapie, met een passend implementatieplan en business modelling.
