Oxytocin is a key hormone in breastfeeding. No recent review on plasma levels of oxytocin in response to breastfeeding is available. Systematic literature searches on breastfeeding induced oxytocin levels were conducted 2017 and 2019 in PubMed, Scopus, CINAHL, and PsycINFO. Data on oxytocin linked effects and effects of medical interventions were included if available. We found 29 articles that met the inclusion criteria. All studies had an exploratory design and included 601 women. Data were extracted from the articles and summarised in tables. Breastfeeding induced an immediate and short lasting (20 minutes) release of oxytocin. The release was pulsatile early postpartum (5 pulses/10 minutes) and coalesced into a more protracted rise as lactation proceeded. Oxytocin levels were higher in multiparous versus primiparous women. The number of oxytocin pulses during early breastfeeding was associated with greater milk yield and longer duration of lactation and was reduced by stress. Breastfeeding-induced oxytocin release was associated with elevated prolactin levels; lowered ACTH and cortisol (stress hormones) and somatostatin (a gastrointestinal hormone) levels; enhanced sociability; and reduced anxiety, suggesting that oxytocin induces physiological and psychological adaptations in the mother. Mechanical breast pumping, but not bottle-feeding was associated with oxytocin and prolactin release and decreased stress levels. Emergency caesarean section reduced oxytocin and prolactin release in response to breastfeeding and also maternal mental adaptations. Epidural analgesia reduced prolactin and mental adaptation, whereas infusions of synthetic oxytocin increased prolactin and mental adaptation. Oxytocin infusion also restored negative effects induced by caesarean section and epidural analgesia. Oxytocin is released in response to breastfeeding to cause milk ejection, and to induce physiological changes to promote milk production and psychological adaptations to facilitate motherhood. Stress and medical interventions during birth may influence these effects and thereby adversely affect the initiation of breastfeeding.

Norway has been considered iodine replete for decades; however, recent studies indicate reemergence of inadequate iodine status in different population groups. We assessed iodine status in pregnant women based on urinary iodine concentration (UIC), urinary iodine excretion (UIE), and iodine intake from food and supplements. In 804 pregnant women, 24-h iodine intakes from iodine-rich foods and iodine-containing supplements were calculated. In 777 women, iodine concentration was measured in spot urine samples by inductively coupled plasma/mass spectrometry (ICP-MS). In addition, 49 of the women collected a 24-h urine sample for assessment of UIE and iodine intake from food frequency questionnaire (FFQ). Median UIC was 92 µg/L. Fifty-five percent had a calculated iodine intake below estimated average requirement (EAR) (160 µg/day). Iodine intake from food alone did not provide the amount of iodine required to meet maternal and fetal needs during pregnancy. In multiple regression models, hypothyroidism, supplemental iodine and maternal age were positively associated with UIC, while gestational age and smoking were negatively associated, explaining 11% of the variance. This study clearly shows that pregnant women in the Oslo area are mild to moderate iodine deficient and public health strategies are needed to improve and secure adequate iodine status.

Persons with autism spectrum disorder (ASD) and/or intellectual disability (ID) have difficulties in planning, organising and coping with change, which impedes the learning of daily living skills (DLSs), social participation and self-management across different environmental settings. Assistive technologies (ATs) is a broad term encompassing devices and services designed to support individuals with disabilities, and if used in a self-controlled manner, they may contribute inclusion in all domains of participation. This comprehensive literature review aims to critically assess and unify existing research that investigates the use of assistive technology within the practical domain for individuals with ASD and/or ID. The 18 relevant studies included in this review highlighted the benefits of AT for social participation and independence in daily activities of individuals with ASD and/or ID. Professionals working with this target group should be knowledgeable of the speedy progress of AT products and the potential of persons with ASD and/or ID to use mainstream devices to meet their individual needs. This awareness provides an opportunity to advocate for the universal benefits of AT for everyone. Technologies such as virtual reality, mobile applications and interactive software have been shown to improve DLSs, communication and social interaction. These tools offer engaging, user-friendly platforms that address the specific needs of these individuals, enhancing their learning and independence.

The proportion of elderly people in the population is increasing, presenting a number of new challenges in society. The purpose of this qualitative study was to investigate how elderly persons with motoric eating difficulties perceive and perform their food and meal practices in everyday life. By using Goffman's concept of performance as a theoretical framework together with Bourdieu's thinking on habitus, a deeper understanding of food and meal practices is obtained. Semi-structured interviews were conducted with 14 elderly people (aged between 67 and 87 years) and meal observations were carried out with 11 of these people. Participants were found to manage food and meal practices by continuously adjusting and adapting to the new conditions arising as a result of eating difficulties. This was displayed by conscious planning of what to eat and when, avoiding certain foods and beverages, using simple eating aids, but also withdrawing socially during the meals. All these adjustments were important in order to be able to demonstrate proper food and meal behaviour, to maintain the façade and to act according to the perceived norms. As well as being a pleasurable event, food and meals were also perceived in terms of being important for maintaining health and as ‘fuel’ where the main purpose is to sustain life. This was strongly connected to the social context and the ability to enjoy food and meals with family members and friends, which appeared to be particularly crucial due to the impending risk of failing the meal performance.

Technology-assisted physical activity interventions for older adults in their home-based environment have been used to promote physical activity. While previous reviews focused on health-related outcomes of such interventions, this scoping review explores the characteristics of the technology in relation to the characteristics of populations, exercise types and usability in terms of adverse events, drop-outs, adherence and user experience. We identified 8496 sources. After title and abstract screening, 455 full texts were assessed, and 148 were included, representing 12,717 participants aged 74 (SD 6) years. In total, 93 (63%) sources reported on the population’s health status. The main purpose of the interventions was balance (51%), and strength and power (43%) and intervention purposes were not related to embedded technology. In studies where the participant’s health status was reported as healthy, 53% implemented exergames compared to only 27% in studies with participants with a clinical condition. Mobile apps (20%) and trackers (11%) were implemented likewise in both groups. The technology was embedded to provide continuous exercise information (27%) and exercise feedback (27%) or to record real-time movement data (26%). Adverse events were reported in 68 (46%) of the sources with three quarters (49 sources) reporting no adverse events. Only 2 mild events were related to technology. Dropout rates were reported in 100 (68%) studies, with no differences between intervention (16±16%) and control (14±12%) groups. Dropout reasons related to technology in 3%. Adherence was reported in 78 studies (53%) and was slightly higher in the intervention group (80±18%) compared to the control group (71±25%). A significantly higher adherence was found between interventions that were tailored (83 ± 15%) versus those that were not (75±21%). General enjoyment of the technology was captured in 55 studies (37%) and was rated positive (91%), neutral (7%) or negative (2%). Occasionally reported wishes were related to goal setting, feedback, technical support, exercise variation, and social setting. In conclusion, various technologies were successfully used in healthy and clinical older populations. The embedded technology was not a reason for additional dropouts, lead to slightly better adherence, and adverse events were rarely related to technology. When assessed, the technology was well accepted and positively enjoyed.
