PretermConnect: Leveraging mobile technology to mitigate social disadvantage in the NICU and beyond.
Seminars in perinatology
Preterm birth (PTB) - delivery prior to 37-weeks gestation - disproportionately affects low-income and minority populations and leads to substantial infant morbidity and mortality. The time following a PTB represents an optimal window for targeted interventions that encourage mothers to prioritize their own health and that of their babies. Healthcare teams can leverage digital strategies to address maternal and infant needs in this postpartum period, both in the neonatal intensive care unit and beyond. We therefore developed PretermConnect, a mobile app designed to educate, engage, and empower women at risk for PTB. This article describes the participant-centered design approach of PretermConnect, with preliminary findings from focus groups and co-design sessions in different community settings and suggested future directions for mobile technologies in population health. Apps such as PretermConnect can mitigate social disadvantage by serving as remote monitoring tools, providing social support, preventing recurrent PTB and lowering infant mortality rates.

Promoting infant mental health in the neonatal intensive care unit (NICU): A review of nurturing factors and interventions for NICU infant-parent relationships.
Early human development
Premature and medically vulnerable infants experience early and sometimes prolonged separation from their parents, intrusive and unnatural environments, painful and distressing procedures, difficulties with physiological regulation, increased biological and neurological vulnerabilities, and grow up to have higher rates of neurocognitive and psychosocial difficulties. Parents of infants born prematurely or with medical vulnerabilities, in turn, experience significant distress and are a psychiatrically vulnerable population, with very high rates of depression, anxiety, and posttraumatic stress disorder. The combination of these factors cause significant challenges for some of these infants and parents in developing an early optimal relationship and connection. Given the critical importance of early relationships with main caregivers for infant mental health and long-term developmental outcomes, we review various targets of intervention to promote healthy infant and parent mental health and bonding thereby facilitating an optimal infant-parent relationship in the NICU population.

Former NICU Families Describe Gaps in Family-Centered Care.
Qualitative health research
Care and outcomes of infants admitted to neonatal intensive care vary and differences in family-centered care may contribute. The objective of this study was to understand families' experiences of neonatal care within a framework of family-centered care. We conducted focus groups and interviews with 18 family members whose infants were cared for in California neonatal intensive care units (NICUs) using a grounded theory approach and centering the accounts of families of color and/or of low socioeconomic status. Families identified the following challenges that indicated a gap in mutual trust and power sharing: conflict with or lack of knowledge about social work; staff judgment of, or unwillingness to address barriers to family presence at bedside; need for nurse continuity and meaningful relationship with nurses and inconsistent access to translation services. These unmet needs for partnership in care or support were particularly experienced by parents of color or of low socioeconomic status.

Assessing speech exposure in the NICU: Implications for speech enrichment for preterm infants.
Journal of perinatology : official journal of the California Perinatal Association
Quantify NICU speech exposure over multiple days in relation to NICU care practices.Continuous measures of speech exposure were obtained for preterm infants (n = 21; 12 M) born <34 weeks gestational age in incubators (n = 12) or open cribs (n = 9) for 5-14 days. Periods of care (routine, developmental) and delivery source (family, medical staff, cuddler) were determined through chart review.Infants spent 13% of their time in Care, with >75% of care time reflecting developmental care. Speech counts were higher during care than no care, for mature vs. immature infants, and for infants in open cribs vs. incubators. Family participation in care ranged widely, with the highest speech counts occurring during periods of intentional voice exposure.Care activities represent a small portion of NICU experiences. Speech exposure during Developmental Care, especially with intentional voice exposure, may be an important source of stimulation. Implications for care practices are discussed.

Effect of reading to preterm infants on measures of cardiorespiratory stability in the neonatal intensive care unit.
Journal of perinatology : official journal of the California Perinatal Association
OBJECTIVE: To evaluate the impact of parental bedside reading (PR) on cardio-respiratory (CR) stability of preterm infants.METHODS/STUDY DESIGN: Prospective examination of the impact of PR on CR stability in preterm NICU infants. CR data from 3 time points: pre-reading (3 and 1h before reading), during PR, and post-reading (1h after reading) were compared.RESULTS: Eighteen infants born at 23-31wks gestation, and 8 to 56 days old, were enrolled. Episodes of oxygen desaturation to <85% were fewer during PR as compared to the pre-reading periods and were fewer with live and maternal PR.CONCLUSION: Preterm infants showed fewer desaturation events less than 85% during PR than prior to reading exposure. This effect persisted up to 1h after reading exposure. Desaturation events were fewer with live and maternal PR. Voice exposure can be an important way for parents to participate in the care of their preterm infants.

Premature Infants Conceived with Assisted Reproductive Technology: An Analysis of Infant Morbidity, Compared with Infants Conceived Naturally.
American journal of perinatology
OBJECTIVE: This article evaluates the morbidity of infants born via assisted reproductive technology (ART) compared with matched naturally conceived infants.STUDY DESIGN: This is a retrospective review of maternal and infant data among inborn infants conceived via ART and matched control infants born at 30 to 34 weeks' gestational age (GA) between 2006 and 2012. Data were analyzed using paired t-test or Wilcoxo-Mann-Whitney test for continuous and Fisher's exact test for categorical variables. p-Value of<0.05 was considered significant.RESULT: Of 120 study infants, 60 were conceived via ART and 60 naturally. Control infants were matched for GA, gender, race, and multiple gestations. ART infants required more respiratory support and took longer to reach full feeds compared with control infants.CONCLUSION: Infants born via ART are physiologically more immature with more intensive care needs than naturally conceived infants of similar gestation, potentially increasing health care costs. This immaturity should be considered when planning early delivery in these pregnancies.

Pilot study of dornase alfa (Pulmozyme) therapy for acquired ventilator-associated infection in preterm infants.
Evaluate the feasibility, safety, and efficacy of adjunctive treatment with dornase alfa in preterm patients with ventilator-associated pulmonary infection (VAPI) compared to standard care.We hypothesize that therapy with dornase alfa will be safe and well tolerated in the preterm population with no worsening of symptoms, oxygen requirement, or need for respiratory support.Prospective, randomized, blinded, pilot study comparing adjunctive treatment with dornase alfa to sham therapy. In addition to standard care, infants were randomized to receive dornase alfa 2.5 mg nebulized via endotracheal tube (ETT) every 12 hr for 7 days or sham therapy. ETT secretion gram stain and culture and chest X-ray (CXR) findings were evaluated. Respiratory support data were downloaded from the ventilator.Fourteen infants developed VAPI between 2012 and 2014; 11 enrolled in the study. Six received dornase alfa and five received sham therapy. Average gestational age at birth was 25 weeks and age at study entry was 31 days. There were no differences in demographics, ETT white blood cell count (WBC), CXR, or mean airway pressure (MAP) between the two groups. There was a trend towards decreased oxygen requirement (FiO2) in the treatment group that did not reach statistical significance. No side effects were observed in the treatment group.Treatment with dornase alfa is safe and treated infants had some improvement in FiO2 requirement but no improvement in MAP. A larger randomized trial is needed to evaluate the efficacy of this therapy. Pediatr Pulmonol. 2016; 9999:XX-XX. © 2016 Wiley Periodicals, Inc.
