Functional Connectivity of the Human Brain in Utero

The brain is subject to dramatic developmental processes during the prenatal period. Nevertheless, information about the development of functional brain networks during gestation is scarce. Until recently it has not been possible to probe function in the living human fetal brain. Advances in functional MRI have changed the paradigm, making it possible to measure spontaneous activity in the fetal brain and to cross-correlate functional signals to attain information about neural connectional architecture across human gestation. We summarize the earliest MRI studies of fetal neural functional connectivity and highlight unique challenges and limitations inherent in the technique. In addition, we discuss future directions to unlock the potential of fetal brain functional MRI research.

Olfaction in the fetal and premature infant: functional status and clinical implications

This article considers olfaction as a functioning source of information for the fetus and the neonate, born on term or prematurely. It aims to present how odors are involved in the sensory continuity between the prenatal and postnatal environments and how they influence the earliest adaptive responses of newborns in the realms of self-regulation, emotional balance, feeding, and social interactions.Finally, it evaluates odors as sensory means to ameliorate the physiologic and behavioral responses of preterm infants to the adverse impacts of separation from mother, nonoral feeding, or iatrogenic distress.

Pain in the very preterm baby: 'suffer little children?'

Increases in medical expertise and technological advances have enabled the survival of very preterm babies who form a new and growing population. Comparisons between the foetus, full-term baby and the very preterm baby indicate that by the time the foetus is of 23 weeks gestation, many of the abilities, for example, sensing touch, hearing, seeing, moving and even learning may be common to all three. Thus, the very preterm infant who has been described as a unique organism, is not passive, but is a sentient being who is unlikely to survive without the medical and technical support of the Neonatal Intensive Care Unit (NICU) where he/she is exposed to frequent and regular medical procedures. Many of these procedures would be, for any normal, fully developed human being at best uncomfortable and at worst painful. Reviews within the past 10 years have shown that the neurochemical, anatomic and functional systems of newborns are developed enough to perceive pain. More importantly, rat pup studies have indicated that not only may the very preterm baby experience pain but it may experience it more intensely than the more mature infant. Moreover, there may be serious consequences of repeated painful medical intervention. Alleviation of pain and/or distress in very preterm infants is, therefore, an important issue.

TAC-TIC therapy: a non-pharmacological stroking intervention for premature infants

This paper describes a non-pharmacological stroking intervention which has been used with premature infants. This intervention is referred to as Touching and Caressing, Tender in Caring (TAC-TIC) therapy. Some of the beneficial outcomes resulting from TAC-TIC in healthy preterms are outlined, along with some of the initial findings from research using the therapy with the high-risk ventilated premature neonate. Current research has been conducted using a psychoneuroimmunological framework and preliminary findings have indicated stabilized cardiovascular responses, enhanced secretory immunity and increased frequency of occurrence of comfort behaviours as a result of TAC-TIC therapy.

The role of relationship-based developmentally supportive newborn intensive care in strengthening outcome of preterm infants

This article details the conceptual framework, clinical application, and efficacy of a relationship-based developmentally supportive approach to newborn intensive care referred to as NIDCAP (Newborn Individualized Developmental Care and Assessment Program). Outcomes of the approach are reported in regard to infant health and development, reduction of hospital costs, and family adaptation. The approach is guided by a neurodevelopmental framework for understanding preterm infants and depends on the capacities of professionals to collaborate with one another and with families in support of the infants' medical, developmental, and emotional well-being. The primary vehicle for clinical implementation is detailed behavioral observation with subsequent recommendations for individualized caregiving based on the infant's current functioning and apparent developmental goals. A series of essential components of developmentally oriented caregiving are described, including strategies for coordinated discharge planning, and linkage to community services. The voices of individual clinicians highlight the process of change from protocol-based to relationship-based care.

Effectiveness of individualized neurodevelopmental care in the newborn intensive care unit (NICU)

The individual infant's neurodevelopmental process provides an integrative framework for the delivery of medical care needed to assure the infant's survival and quality of outcome. The infant's neurobehavioral functioning and expression provides an opportunity for caregivers to estimate the individual infant's current strengths, vulnerabilities and threshold to disorganization, as well as to identify the infant's strategies in collaborating in his or her best progression. This perspective supports caregivers in seeing themselves in a relationship with the infant, and in considering opportunities to enhance the infant's strengths and reduce apparent stressors in collaboration with the infant and the family. The results of several randomized studies supporting the effectiveness of such a neurodevelopment approach to NICU care will be presented, and suggest implications for staff education and nursery-wide implementation.

The incidence of sleeping problems in preterm and fullterm infants discharged from neonatal special care units: an epidemiological longitudinal study

Anecdotal reports have suggested that sleeping problems are a frequent complaint from parents of preterm infants. This prospective epidemiological study examined the incidence and stability of sleeping problems of very preterm (< 32 weeks gestation at birth), preterm (32-36 weeks gestation) and fullterm infants, all admitted to special care baby units (SCBU) after birth, in comparison to healthy term infants over the first 5 years of life. Preterm infants were found to have fewer and shorter night-wakings at 5 months. No differences in sleeping behaviour compared with healthy term children were found at 20 and 56 months of age. Similar significant, and moderate, stability of nightwaking from one age to the next were found for exSCBU-graduates and healthy fullterm infants. Parental interventions such as staying with the child until sleep and taking the infant into bed af night were related to nightwaking problems and increased parental distress. It is concluded that prematurity, and thus neurological immaturity and special care experience are less important than caretaking behaviour in the development of sleeping problems in both preterm and fullterm infants.

Preterm labour and delivery: psychological sequelae

The psychological care of preterm babies and their families is challenging and at least as demanding for staff as the technical aspects of care. There is growing evidence for the effectiveness of therapeutic interventions in this area, thus ensuring the optimum outcome for the baby, the family and the staff.

Psychosocial interventions for very low birthweight infants: their scope and efficacy

With the burgeoning of infant psychiatry, and the increasing survival and development of cohorts of very low birthweight (VLBW) infants, psychiatrists are becoming increasingly involved with other professionals in designing and implementing early intervention programs. Psychosocial interventions for VLBW infants generally report positive results regardless of the orientation of the practitioners, or the stated goal of the intervention: however, they have often taken place independently of longitudinal research, and sometimes without grounding in theories of infant and family development. This paper first reviews the current state of research and findings related to infant-focussed, parent-directed, and interactional programs. Second, it addresses a number of basic questions to be considered by psychiatrists involved in consulting to neonatal intensive care units, who have to appraise, design or implement intervention programs with this group. Throughout this discussion, it is proposed that the notion of infants at developmental risk needs to be supplemented by that of caregivers at risk, and that the professional boundaries which these distinctions represent need to be overcome.
