Among children, there are substantial ethno-racial minority disparities across a broad range of health-related behaviors, experiences, and outcomes. Addressing these disparities is important, as ...childhood and adolescence establish health trajectories that extend throughout life.
The current study employed a community-based participatory research approach to gain community insight on child health priorities and to frame an intervention aimed at improving the health of minority children. Eight focus groups were conducted among seventy-five African American parents in a Southeastern city. The current study was guided by an ecological theoretical framework.
Although the focus of this investigation was on community identification of child health priorities, participants cited, as root determinants, contextual factors, which included lack of healthy food options, lack of spaces for physical activity, and community violence. These co-occurring factors were related to limited engagement in outdoor activities and physical activity, increased obesity, and poor mental health and coping. Poor parenting was cited as the most substantial barrier to improving child health outcomes, and quality parenting was identified as the most important issue to address for community programs focused on promoting the health and success of children. For improving health outcomes for children in their neighborhoods, establishment of positive social capital and constructive activities were also cited.
These results reinforce social determinants of health as influences on child health outcomes and describe how community engagement can address potential solutions through interventions that resonate with program participants.
•SSTP professionals’ delivery data were analysed with survey data from 2 years after training.•Social identity was associated with delivery of Stepping Stones Triple P in independent ...analysis.•Self-efficacy mediated the relationship between social identity and use of SSTP.
Identifying factors that may contribute to the use of programs following the completion of training by practitioners is of practical and theoretical importance.
This study examined the role of social identity and self-efficacy in contributing to the delivery of an evidence-based parenting program.
A sample of 63 multi-disciplinary professionals trained in the Stepping Stones Triple P-Positive Parenting Program, for parents of children with developmental disability, as part of a statewide roll-out were interviewed two years after training. Data on the number of hours of delivery during the 2-year period was analysed along with quantitative data obtained during interviews that assessed professionals’ self-efficacy and social identity as a Stepping Stones professional.
Social identity was associated with the use of SSTP in an independent analysis, but the association was no longer significant when other factors were included in a regression model. Self-efficacy predicted the use of SSTP and was found to be a mediator in the relationship between social identity and use of SSTP.
This first investigation into the role of social identity in the implementation of evidence-based parenting programs showed that social identity could play an important role. The role of self-efficacy in predicting program use was further supported in this study and the mediator function of self-efficacy is explored. The practical and theoretical implications of the role of self-efficacy and social identity in the training of professionals are discussed.

"And then--the Veil. It drops as drops the night on southern seas--vast, sudden, unanswering. There is Hate behind it, and Cruelty and Tears. As one peers through its intricate, unfathomable pattern ...of ancient, old, old design, one sees blood and guilt and misunderstanding. And yet it hangs there, this Veil, between Then and Now, between Pale and Colored and Black and White -- between You and Me." W.E.B. DuBois, Darkwater: Voices from within the Veil, 1920 "As the promoters of Jamestown.
Abstract only
Androgen‐induced gene 1 (AIG1) and Androgen‐dependent TFPI‐regulating protein (ADTRP) are atypical transmembrane hydrolases that rely on a catalytic threonine for their enzymatic ...activity.
In vitro
characterization of AIG1 and ADTRP in lysates and cells identified fatty acid ester of hydroxy fatty acids (FAHFAs) as their putative substrates. Here, we generate ADTRP knockout (
Adtrp
‐KO), AIG1 knockout (
Aig1‐
KO), and ADTRP/AIG1 double deficient (DKO) mice using CRISPR‐Cas9 technology to test whether these enzymes regulate FAHFAs
in vivo
. AIG1, ADTRP, or a deficiency in both enzymes leads to decreased FAHFA hydrolytic activity in tissue lysates. Quantitative measurement of FAHFA levels in several tissues revealed increased FAHFA levels in brown adipose tissue (BAT), subcutaneous adipose tissue (SQWAT), and perigonadal WAT (PGWAT) of
Adtrp‐
KO mice consistent with the loss of FAHFA degrading activity. Furthermore, contribution by AIG1 was modest and only observed in the kidney and BAT of DKO mice. Lipidomics of tissues from knockout and wild type control mice detected no significant changes in other lipid classes to indicate that these enzymes are specific for FAHFA substrates. Furthermore, we developed a potent and selective, dual AIG1/ADTRP inhibitor to enable pharmacological interrogation of these enzymes
in vivo
. Chemical inhibition of AIG1 and ADTRP raised FAHFA levels demonstrating acute regulation of FAHFAs. In aggregate, the results establish AIG1 and ADTRP as the only endogenous FAHFA hydrolases known, and describe resources (mice, inhibitors) needed to elucidate the biochemical and physiological role of these exciting enzymes.

To assess sex-specific differences in early brain structure and function of preterm infants after red blood cell (RBC) transfusions.
A single-center subset of infants with a birth weight <1000 g and ...gestational age 22-29 weeks were enrolled from the National Institute of Child Health and Human Development’s Neonatal Research Network Transfusion of Prematures Trial. Hemoglobin (Hb) concentration obtained directly before each transfusion (pretransfusion Hb ptHb) was obtained longitudinally throughout each infant’s neonatal intensive care unit stay and used as a marker of degree of anemia (n = 97). Measures of regional brain volumes using magnetic resonance imaging were obtained at ∼40 weeks postmenstrual age or at hospital discharge, if earlier (n = 29). Measures of brain function were obtained at 12 months corrected age using the Bayley Scales of Infant & Toddler Development, 3rd Edition (n = 34).
PtHb was positively correlated with neonatal cerebral white matter volume in males (B = +0.283; P = .006), but not females (B = −0.099; P = .713), resulting in a significant sex interaction (P = .010). Bayley-III gross motor scores and a pooled mean score were significantly lower in association with higher ptHb in females (gross motor score: B = −3.758; P = .013; pooled mean score: B = −1.225; P = .030), but not males (gross motor score: B = +1.758; P = .167; pooled mean score: B = +0.621; P = .359). Higher ptHb was associated with descriptively lower performance on multiple Bayley-III subscales in females, but not in males.
This study demonstrates sex-specific associations between an early marker of anemia and RBC transfusion status (ie, ptHb) with both neonatal white matter volume and early cognitive function at age 12 months in preterm infants.

Current guidelines suggest that cholecystectomy during the third trimester of pregnancy is safe for both the woman and the fetus. However, no population-based study has examined this issue. The aim ...of this analysis was to compare the results of cholecystectomy during the third trimester of pregnancy with outcomes in women operated on in the early postpartum period in a large population.
The California Office of Statewide Health Planning and Development database was queried from 2005 to 2014. Women undergoing cholecystectomy during the third trimester of pregnancy (n = 403) were compared with those having this procedure in the 3 months post partum (n = 17,490). Patient demographics as well as maternal delivery and cholecystectomy-related outcomes were compared by standard statistics as well as after adjustments for age, race, comorbidities, insurance status, and hospital setting.
Women who underwent cholecystectomy during the third trimester were older (27 vs 25 years; p < 0.001), but did not differ in race or insurance status. Cholecystectomy during pregnancy was more likely to require hospitalization (85% vs 63%; p < 0.001) and more likely to be performed open (13% vs 2%; p < 0.001). Composite maternal outcomes (odds ratio 1.88; p < 0.001), including preterm delivery (odds ratio 2.05; p < 0.001) as well as length of hospital stay (+0.83 days; p < 0.001) and readmissions (odds ratio 2.05; p = 0.002), were all significantly increased when cholecystectomy was performed during pregnancy.
Maternal delivery and procedure-related outcomes were worse when cholecystectomy was performed during the third trimester of pregnancy. Preterm delivery, which is associated with multiple adverse infant outcomes, was increased in third-trimester women. Whenever possible, cholecystectomy should be delayed until the postpartum period.
Open top chambers (OTCs) were adopted as the recommended warming mechanism by the International Tundra Experiment network in the early 1990s. Since then, OTCs have been deployed across the globe. ...Hundreds of papers have reported the impacts of OTCs on the abiotic environment and the biota. Here, we review the impacts of the OTC on the physical environment, with comments on the appropriateness of using OTCs to characterize the response of biota to warming. The purpose of this review is to guide readers to previously published work and to provide recommendations for continued use of OTCs to understand the implications of warming on low stature ecosystems. In short, the OTC is a useful tool to experimentally manipulate temperature; however, the characteristics and magnitude of warming varies greatly in different environments; therefore, it is important to document chamber performance to maximize the interpretation of biotic response. When coupled with long-term monitoring, warming experiments are a valuable means to understand the impacts of climate change on natural ecosystems.
The Arctic is warming at an alarming rate, leading to earlier spring conditions and plant phenology. It is often unclear to what degree changes in reproductive fitness (flower, fruit, seed ...production) are a direct response to warming versus an indirect response through shifting phenology. This study aims to quantify the relative importance of these direct and indirect pathways and project the net effects of warming on plant phenology and reproductive fitness under current and future climate scenarios.
We used two long-term datasets on twelve tundra species in the Canadian Arctic as part of the International Tundra Experiment (ITEX). Phenology and reproductive fitness were recorded annually on tagged individual plants at both Daring Lake, Northwest Territories (64.87, -111.58) and Alexandra Fiord, Nunavut (78.83, -75.80). Plant species encompass a wide taxonomic diversity across a range of plant functional types with circumpolar/boreal distributions. We use Hierarchical Bayesian Structural Equation models to compare the direct and indirect effects of climate warming on phenology and reproductive fitness across species, sites and years.
We find that warming, both experimental and ambient, drives earlier flowering across species, which leads to higher numbers of flowers and fruits produced, reflecting directional phenotypic selection for earlier flowering phenology. Furthermore, this indirect effect of climate warming mediated through phenology was generally ~2-3x stronger than the direct effect of climate on reproductive fitness. Under future climate predictions, individual plants showed a ~2 to 4.5-fold increase in their reproductive fitness (flower counts) with advanced flowering phenology.
Our results suggest that, on average, the benefits of early flowering, such as increased development time and subsequent enhanced reproductive fitness, may outweigh its risks. Overall, this work provides important insights into population-level consequences of phenological shifts in a warming Arctic over multi-decadal time scales.
