The present study is an examination of cue-directed tactile stimulation (CTDS), administered by mothers and NICU nurses, on infant and maternal stress reactivity, infant immune system functioning, maternal parenting cognitions, and parenting competence.
The overarching aim of this study is to assess the effects of a program of mother-delivered, cue-based infant massage on stress reactivity in the mother-infant dyad, and on other measures of mother-infant functioning. The study has several interrelated objectives:
1. To evaluate the short-term effects of infant massage intervention on infant and maternal stress reactivity from assays of maternal and infant salivary cortisol, and cortisol levels in mothers' breast milk.
2. To examine the impact of mother-delivered infant massage on the development of infant resistance to infectious pathogens and antibody-based protective immunity in response to routine scheduled vaccinations, and to examine if the degree of immunity is mediated by infant stress reactivity.
3. To examine the impact of mother-delivered infant massage, and of changes in stress reactivity in response to massage, on infant physiological functioning (vagal tone, heart rate variability), infant physical development (weight, height, and head circumference), mothers' perception of infant temperament and infant state regulation, parenting self-efficacy, symptoms of depression and anxiety, and mother-infant interaction.
4. To examine associations between cortisol levels in mothers' saliva, mothers' breast milk, and infants' saliva. Establishing such linkages would support recent animal data suggesting that infant glucocorticoid levels can be affected by glucocorticoid levels transferred to the infant in mother's milk.
5. To examine whether a single nucleotide polymorphism (SNP) in three candidate genes (Mu opioid receptor, brain-derived neurotropic factor, and vasopressin V1b receptor), each associated with hypothalamic-pituitary-adrenal axis (HPA) functioning, moderates the effects of infant massage on stress-related outcomes.

Two groups of preterm infants with birth weight equal to or less than 1500 grams will be studied. One group will receive the standard care and the other will receive standard care plus mat...
We hypothesized an association between auditory stimulus structure and activity in the brain that underlies infant auditory preference. In a within-infant design, we assessed brain activity to female ...
Deviant stimuli within a standard, frequent stimulus train induce a cortical somatosensory mismatch response (SMMR). The SMMR reflects the brain's automatic mechanism for the detection of change in a ...
Despite a long history of research, the development of synthetic tactual aids to support the communication of speech has proven to be a difficult task. The current paper describes a new tactile speech...

Onset of OBSTETRIC LABOR before term (TERM BIRTH) but usually after the FETUS has become viable. In humans, it occurs sometime during the 29th through 38th week of PREGNANCY. TOCOLYSIS inhibits premature labor and can prevent the BIRTH of premature infants (INFANT, PREMATURE).
Diseases that occur in PREMATURE INFANTS.
A chronic lung disease developed after OXYGEN INHALATION THERAPY or mechanical ventilation (VENTILATION, MECHANICAL) usually occurring in certain premature infants (INFANT, PREMATURE) or newborn infants with respiratory distress syndrome (RESPIRATORY DISTRESS SYNDROME, NEWBORN). Histologically, it is characterized by the unusual abnormalities of the bronchioles, such as METAPLASIA, decrease in alveolar number, and formation of CYSTS.
Stress is caused by your perception of situations around you and then the reaction of your body to them. The automatic stress response to unexpected events is known as 'fight or flight'. Discovered by Walter Cannon in 1932, it is the release of h...
An antibody is a protein produced by the body's immune system when it detects harmful substances, called antigens. Examples of antigens include microorganisms (such as bacteria, fungi, parasites, and viruses) and chemicals. Antibodies may be produc...
