Financial Support to Medicaid-Eligible Mothers Increases Caregiving for Preterm Infants.

OBJECTIVES: To assess the impact of financial support on maternal caregiving activities for preterm infants. METHODS: We conducted a small randomized controlled trial (RCT) in two Massachusetts Neonatal Intensive Care Units (NICUs). We enrolled 46 Medicaid-eligible mothers of preterm infants between January 2017 and June 2018 and randomly assigned them to a treatment group (up to 3 weekly financial transfers of $200 each while their infant was in the hospital) or a control group. We collected hospital-record data while the infant was admitted. The primary outcome was a binary variable indicating skin-to-skin care (STSC) was provided during a hospital day. Secondary outcomes included daily maternal visitation, daily provision of breastmilk, neonatal growth and length of stay (LOS). Multilevel generalized linear models with random effects were used to estimate treatment effects on daily maternal behaviors and ordinary least squares models were used to estimate impacts on neonatal growth and LOS. RESULTS: We assigned 25 women to the intervention and 21 to the control and observed them over 703 days of their infants' hospitalization. Mothers who received financial support were more likely to provide STSC (adjusted risk ratio: 1.85; 95% confidence interval [CI] 1.31-2.62) and breastmilk (adjusted risk ratio: 1.36; 95% CI 1.06-1.75) while their infant was in the NICU. We see no statistically significant impact on neonatal growth outcomes or LOS, though estimated confidence intervals are imprecise. CONCLUSIONS: Our evidence demonstrates the potential for financial support to increase mothers' engagement with caregiving behaviors for preterm infants during the NICU stay.

Caregiving can be costly: A qualitative study of barriers and facilitators to conducting kangaroo mother care in a US tertiary hospital neonatal intensive care unit.

BACKGROUND: Preterm birth is a leading cause of morbidity and mortality in children under five and often requires a newborn to have an extended stay in a neonatal intensive care unit (NICU). Maternal engagement, such as visiting the NICU to provide kangaroo mother care (KMC), can improve outcomes for preterm infants but requires significant investment of time and resources. This study sought to understand barriers and facilitators to provision of KMC in the NICU. METHODS: We conducted semi-structured in-depth interviews with mothers of preterm infants (N = 20) at a large academic medical center in Massachusetts. A series of open-ended interview questions were designed to elicit all aspects of mothers' experiences and to understand how these experiences influence provision of KMC. All interviews were recorded and transcribed verbatim. We conducted an inductive thematic analysis to identify themes in the data with a focus on the barriers and facilitators of KMC provision in the NICU. RESULTS: Findings show that engaging in KMC is heavily influenced by the mental, emotional, and physical effects of preterm birth on the birth mother, such as stress around preterm birth and difficulty recovering from birth. These challenges are compounded by structural barriers such as costly accommodations, unreliable transportation, lack of child care, and inadequate maternity leave policies that limit the frequency and duration of KMC and parental ability to provide care. CONCLUSIONS: A complex array of mental, emotional, physical, and structural factors determine a mother's ability to visit the NICU and provide kangaroo mother care. Providing social supports, such as improved maternity leave policies and reliable hospital access through child care, accommodation, and transportation services, may address the structural barriers that inhibit KMC, reduce burdensome costs, and improve the health of mothers and their preterm infants.

Ethnic differences in behavioral and physiological indicators of sensitivity to threat.

The clinical presentation of anxiety may differ between Hispanics/Latinx (H/L) and non-H/L, although findings on ethnic differences in self-reported anxiety symptoms have been mixed. Fewer studies have focused on ethnic differences in quick and relatively automatic laboratory-assessed indicators of anxiety symptoms, which have the potential to be more objective indicators than self-report. Therefore, the present study examined ethnic differences in two laboratory-assessed indicators of threat sensitivity (an important transdiagnostic mechanism of anxiety): attentional bias to threat and electromyography startle reactivity to threat. White H/L (n = 117) and White non-H/L (n = 168) adults who were matched on demographics and lifetime psychopathology (including anxiety) completed a dot-probe task to assess attentional bias to threat and the No-Predictable-Unpredictable threat (NPU) task to assess startle reactivity to threat. Results indicated that H/L displayed less Slow OrientationRB (ß = -0.27, p = 0.032, R2ß∗ = 0.02), and increased Slow DisengagementRB (ß = 0.31, p = 0.016, R2ß∗ = 0.02) compared to non-H/L. H/L exhibited blunted overall startle compared to non-H/L (ß = -0.30, p = 0.014, R2ß∗ = 0.02), but groups did not differ in startle reactivity to either predictable or unpredictable threat. In summary, H/L and non-H/L may differ in their experience and presentation of anxiety symptoms and such differences may vary across indicators of sensitivity to threat.

The impact of aversive context on early threat detection in trauma exposed individuals and associations with post-traumatic stress symptoms.

Introduction: Prolonged attentional bias to threat (AB) is associated with posttraumatic stress symptoms (PTSS). However, it is unclear whether this relationship extends to early threat detection (elicited by masked stimuli) and/or varies if AB is measured during an aversive context. Methods: Two trauma-exposed samples of either intervention-seekers (N = 50) or community members (N = 98) completed a masked dot-probe task to measure early AB to angry faces in safe vs. aversive contexts (i.e., during threat of aversive noises). Results: Linear mixed effects models showed that an aversive context increased the orienting responses in both samples; however, PTSS did not moderate these effects in either sample. Limitations: Sample size and heterogeneity of trauma-type may have impacted effect of PTSS on AB. Conclusion: These results highlight the importance of assessing AB in varying contexts and examining generalizability across populations. Given prior research, the results also suggest that increased AB in PTSS may only be present for later attentional processes rather than early threat detection, at least with behavioral methods.
