Sleep disturbances in depressed pregnant women and their newborns
Pregnant women (N= 253) were recruited during their second trimester of pregnancy (M= 22.3 weeks gestation) and assigned to
depressed (N= 83) and non-depressed groups based on a SCID diagnosis of depression. They were then given self-report measures on sleep disturbance, depression, anxiety and anger, and their urine was assayed for norepinephrine and cortisol. These measures were repeated during their third trimester (M= 32.4 weeks). Their newborns were then observed during sleep. During both the second and third trimesters, the depressed women had more sleep disturbances and higher depression, anxiety and anger scores.
They also had higher norepinephrine and cortisol levels. The newborns of the depressed mothers also had more sleep disturbances including less time in deep sleep and more time in indeterminate (disorganized) sleep, and they were more active and cried/fussed more.We would like to thank the parents and infants who participated in this study.

Prenatal cortisol, prematurity and low birthweight
Three hundred depressed pregnant women were recruited at approximately 20 weeks gestation. They were then divided by
a median split into high and low urinary cortisol level groups. The high cortisol group had higher CES-D depression scores
and higher inhibition (BIS) scores prenatally. Their fetuses had smaller head circumference, abdominal circumference, biparietal diameter and fetal weight. The high cortisol group neonates were shorter gestational age and lower birthweight and they had lower Brazelton habituation and higher Brazelton reflex scores. Discriminant function analyses suggested that cortisol levels more accurately classified short gestation and low birthweight groups than CES-D depression scores.National Center for Complementary and Alternative Medicine (NCCAM) - (#AT01585).National Institute of Mental Health (NIMH), Senior Scientist Award - (MH #00331), (MH #46586).March of Dimes - Grant (#12-FY03-48)
Prenatal serotonin and neonatal outcome: brief report
The purpose of the present study was to determine the relationships between prenatal serotonin levels and other biochemical values during pregnancy as well as their relationships to neonatal biochemical and behavioral variables. To address that question, the pregnant women were divided into the top and bottom tertiles based on their serotonin levels at 20 weeks gestational age
Social and Psychological Factors Associated with Health Care Transition for Young Adults Living with Sickle Cell Disease
Introduction: Due to advances in disease management, mortality rates in children with sickle cell disease (SCD) have decreased. However, mortality rates for young adults (YA) increased, and understanding of social and psychological factors is critical. The aim of this study was to explore factors associated with health care transition experiences for YA with SCD.
Method: This was a qualitative descriptive study. A 45-minute semistructured interview was conducted with 13 YA (M = 21.5 years, SD = 1.73).
Results: Results suggest that social and psychological factors and self-management experiences influence health care transition. Eight themes emerged: “need for accessible support”; “early assistance with goal setting”; “incongruence among expectations, experiences, and preparation”; “spiritual distress”; “stigma”; “need for collaboration”; “appreciation for caring providers”; and “feeling isolated.”
Discussion: Consideration of cultural contexts will guide nurses in supporting health care transition. Designing culturally relevant interventions that address unique needs for YA living with SCD is warranted
Chronic prenatal depression and neonatal outcome
Four hundred and thirty pregnant women were recruited at approximately 22 weeks gestation at prenatal clinics. Of these, 86 (20%) were diagnosed as depressed. The women were seen again at approximately 32 weeks gestation and after delivery. Chronicity of depression was evidenced by continuing high depression scores in those women diagnosed as depressed. Comorbid problems were chronically high anxiety, anger, sleep disturbance, and pain scores. Less optimal outcomes for the depressed women included lower gestational age and lower birthweight of their newborns
Comorbid depression and anxiety effects on pregnancy and neonatal outcome
The effects of comorbid depression and anxiety were compared to the effects of depression alone and anxiety alone on pregnancy mood states and biochemistry and on neonatal outcomes in a large multi-ethnic sample. At the prenatal period the comorbid and depressed groups had higher scores than the other groups on the depression measure. But, the comorbid group had higher anxiety, anger and daily hassles scores than the other groups, and they had lower dopamine levels. As compared to the non-depressed group, they also reported more sleep disturbances and relationship problems. The comorbid group also experienced a greater incidence of prematurity than the depressed, the high anxiety and the non-depressed groups. Although the comorbid and anxiety groups were lower birthweight than the non-depressed and depressed groups, the comorbid group did not differ from the depressed and anxiety groups on birth length. The neonates of the comorbid and depressed groups had higher cortisol and norepinephrine and lower dopamine and serotonin levels than the neonates of the anxiety and non-depressed groups as well as greater relative right frontal EEG. These data suggest that for some measures comorbidity of depression and anxiety is the worst condition (e.g., incidence of prematurity), while for others, comorbidity is no more impactful than depression alone.This research was supported by a Merit

Observation of playa salts as nuclei in orographic wave clouds
During the Ice in Clouds Experiment-Layer Clouds (ICE-L), dry lakebed, or playa, salts from the Great Basin region of the United States were observed as cloud nuclei in orographic wave clouds over Wyoming. Using a counterflow virtual impactor in series with a single-particle mass spectrometer, sodium-potassium-magnesium-calcium-chloride salts were identified as residues of cloud droplets. Importantly, these salts produced similar mass spectral signatures to playa salts with elevated cloud condensation nuclei (CCN) efficiencies close to sea salt. Using a suite of chemical characterization instrumentation, the playa salts were observed to be internally mixed with oxidized organics, presumably produced by cloud processing, as well as carbonate. These salt particles were enriched as residues of large droplets (>19 μm) compared to smaller droplets (>7 μm). In addition, a small fraction of silicate-containing playa salts were hypothesized to be important in the observed heterogeneous ice nucleation processes. While the high CCN activity of sea salt has been demonstrated to play an important role in cloud formation in marine environments, this study provides direct evidence of the importance of playa salts in cloud formation in continental North America has not been shown previously. Studies are needed to model and quantify the impact of playas on climate globally, particularly because of the abundance of playas and expected increases in the frequency and intensity of dust storms in the future due to climate and land use changes
Prenatal dopamine and neonatal behavior and biochemistry
Depressed pregnant women (N=126) were divided into high and low prenatal maternal dopamine (HVA) groups based on a tertile split on their dopamine levels at 20 weeks gestation. The high versus the low dopamine group had lower Center for Epidemiological Studies-Depression Scale (CES-D) scores, higher norepinephrine levels at the 20-week gestational age visit and higher dopamine and serotonin levels at both the 20- and the 32-week gestational age visits. The neonates of the mothers with high versus low prenatal dopamine levels also had higher dopamine and serotonin levels as well as lower cortisol levels. Finally, the neonates in the high dopamine group had better autonomic stability and excitability scores on the Brazelton Neonatal Behavior Assessment Scale. Thus, prenatal maternal dopamine levels appear to be negatively related to prenatal depression scores and positively related to neonatal dopamine and behavioral regulation, although these effects are confounded by elevated serotonin levels.We would like to thank the mothers and infants who participated in this study.

Recommendations to Update the FTC & DOJ’s Guidelines for Collaborations Among Competitors
Existing joint agency guidance from the FTC and DOJ, “Antitrust Guidelines for Collaborations Among Competitors” was written in 2000 and is misaligned with the agencies’ focus on market power considerations and protecting the competitive process. This white paper seeks to provide a rationale and suggestions for revising the collaboration guidelines. We look to examples in other jurisdictions, with an eye to their treatment of sustainability-related collaborations, as many were updated with these considerations in mind. Importantly, we do not recommend that updated guidelines follow international examples in creating explicit sustainability-related carve outs, safe harbors, or exemptions. Due to the complex and expansive definition of sustainability-related private sector activity, exemptions could lead to obfuscation or abuse. However, we think that updated guidance would benefit from including sustainability-related examples of permissible collaborations to better align with modern market realities and societal challenges. We provide concrete recommendations on how to approach various kinds of collaborations, including: information sharing, joint research and development initiatives, joint procurement, and standard setting. We also discuss how updated guidance should move away from efficiencies-based justifications for anti-competitive behavior, as well as consider monopsony dynamics of collaborations, presumptive thresholds, and consolidation concerns
