OBJECTIVES: The aim of the present study was to disentangle the impact of age and that of cancer diagnosis and treatment on functional status (FS) decline in older patients with cancer.MATERIALS AND METHODS: Patients with breast and colorectal cancer aged 50-69years and aged ≥70years who had undergone surgery, and older patients without cancer aged ≥70years were included. FS was assessed at baseline and after 12months follow-up, using the Katz index for activities of daily living (ADL) and the Lawton scale for instrumental activities of daily living (IADL). FS decline was defined as ≥1 point decrease on the ADL or IADL scale from baseline to 12months follow-up.RESULTS: In total, 179 older patients with cancer (≥ 70years), 341 younger patients with cancer (50-69years) and 317 older patients without cancer (≥ 70years) were included. FS decline was found in 43.6%, 24.6% and 28.1% of the groups, respectively. FS decline was significantly worse in older compared to younger patients with cancer receiving no chemotherapy (44.5% versus 17.6%, p<0.001), but not for those who did receive chemotherapy (39.4% versus 30.8%, p=0.33). Among the patients with cancer, FS decline was significantly associated with older age (OR 2.63), female sex (OR 3.72), colorectal cancer (OR 2.81), polypharmacy (OR 2.10) and, inversely, with baseline ADL dependency (OR 0.44).CONCLUSION: Cancer treatment, and older age are important predictors of FS decline. The relation of baseline ADL dependency and chemotherapy with FS decline suggest that the fittest of the older patients with cancer were selected for chemotherapy.

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.

The studies reported on in this thesis addressed the development of suckingpatterns in preterm newborns. Preterm infants often have problems learningto suckle at the breast or to drink from a bottle. It is unclear whether this isdue to their preterm birth or whether it is the consequence of neurologicaldamage. From the literature, as well as from daily practice, we know thatthere is much variation in the time and in the way children start suckingnormally. Factors such as birth weight and gestational age may indeed berisk factors but they do not explain the differences in development. A smallspot-check proved that most hospitals in the Netherlands start infants onoral feeding by 34 weeks’ post-menstrual age (pma). By and large the policyis aimed at getting the infant to rely on oral feeding entirely as soon aspossible. The underlying rationale is to reduce the stay in hospital, and theidea that prolonged tube-feeding delays or even hampers the development ofsucking.

Borstvoeding heeft belangrijke gezondheidseffecten, voor zowel kinderen als moeders. Een halve eeuw geleden vond borstvoeding bijna nooit tegelijk met werk plaats aangezien vrouwen stopten met werken als ze trouwden, maar tegenwoordig werken moeders vaak door. Daarom is het belangrijk om te onderzoeken hoe de combinatie van arbeid en borstvoeding het best kan worden gefaciliteerd. Uit recent onderzoek blijkt namelijk dat de combinatie van werken en borstvoeding één van de belangrijkste redenen is om vroegtijdig te stoppen met borstvoeding. De gebouwde omgeving, in de vorm van kolfkamers, is belangrijk om de combinatie van borstvoeding en werken zo goed mogelijk te ondersteunen. Op dit moment ontbreekt echter kennis over de invloed van de gebouwde omgeving op vrouwen die borstvoeding geven en/of kolven op het werk: dit is dan ook de focus van het huidige promotieonderzoek.
