BACKGROUND: Efforts to understand the developmental pathways for disorganized attachment reflect the importance of disorganized attachment on the prediction of future psychopathology. The inconsistent findings on the prediction of disorganized attachment from the dopamine D4 receptor (DRD4) gene, birth weight, and maternal depression as well as the evidence supporting the contribution of early maternal care, suggest the importance of exploring a gene by environment model. METHODS: Our sample is from the Maternal Adversity, Vulnerability, and Neurodevelopment project; consisting of 655 mother-child dyads...

Background -Despite concerns about adverse neurocognitive events raised by prior trials, pharmacologic PCSK9 inhibition was not associated with neurocognitive effects in a recent phase 3 randomized trial. PCSK9 loss-of-function (LOF) variants that result in life-long exposure to low LDL-C can provide information on the potential long-term effects of low LDL-C on neurocognitive impairment and decline. Methods -We investigated the association between PCSK9 LOF variants and neurocognitive impairment and decline among African-American REasons for Geographic and Racial Differences in Stroke (REGARDS) study participants with (n=241) and without (n=10,454) C697X or Y142X LOF variants...

Mutations in IDH1 are highly prevalent in human glioma. First line treatment is radiotherapy, which many patients often forego to avoid treatment-associated morbidities. The high prevalence of IDH1 mutations in glioma highlights the need for brain-penetrant IDH1 mutant-selective inhibitors as an alternative therapeutic option. Here, we have explored the utility of such an inhibitor in IDH1 mutant patient-derived models to assess the potential therapeutic benefits associated with intracranial 2-HG inhibition...

BACKGROUND: We have shown that intrauterine growth restriction (IUGR) leads to increased preference for palatable foods at different ages in both humans and rodents. In IUGR rodents, altered striatal dopamine signaling associates with a preference for palatable foods. OBJECTIVES: Our aim was to investigate if a multilocus genetic score reflecting dopamine-signaling capacity is differently associated with spontaneous palatable food intake in children according to the fetal growth status...

OBJECTIVE: Disturbed flow (DF) is well-known to induce endothelial dysfunction and synergistically with plasma dyslipidemia facilitate plaque formation. Little is known, however, about the synergistic impact of DF and dyslipidemia on endothelial biomechanics. Our goal was to determine the impact of DF on endothelial stiffness and evaluate the role of dyslipidemia/oxLDL (oxidized low-density lipoprotein) in this process. APPROACH AND RESULTS: Endothelial elastic modulus of intact mouse aortas ex vivo and of human aortic endothelial cells exposed to laminar flow or DF was measured using atomic force microscopy...

BACKGROUND: Although the benefits of statins accrue over time, treatment discontinuation is common. Examining the patterns of statin discontinuation, reinitiation, and persistence after reinitiation among Medicare beneficiaries after hospital discharge for a myocardial infarction may help increase statin use in high-risk patients. METHODS AND RESULTS: Medicare beneficiaries with a statin fill claim within 30 days after hospital discharge for myocardial infarction in 2007 to 2012 (n=158 795) were followed for 182 days post-discharge to identify discontinuation, defined as 60 continuous days without statins available...

BACKGROUND: Less intensive treatment for heart failure with reduced ejection fraction (HFrEF) may be appropriate for patients in long-term care settings because of limited life expectancy, frailty, comorbidities, and emphasis on quality of life. METHODS: We compared treatment patterns between REasons for Geographic And Racial Differences in Stroke (REGARDS) study participants discharged to long-term care versus home following HFrEF hospitalizations. We examined medical records and Medicare pharmacy claims for 147 HFrEF hospitalizations among 80 participants to obtain information about discharge disposition and medication prescriptions and fills...

A mother's cortisol secretion is importantly associated with her own mental health and her infant's cortisol secretion. This study investigated the influences of maternal history of care and maternal DRD2, SLC6A3, and OXTR genotypes on maternal cortisol in the context of infant stress. A community sample of 296 mother-infant dyads completed a maternal separation at infant age 17 months. Maternal salivary cortisol, buccal cells, and self-reported history of care were collected. Multilevel models revealed that history of care had a greater influence on maternal baseline cortisol (but not cortisol trajectory) for mothers with more plasticity alleles of SLC6A3 (10R) and OXTR (G), relative to mothers with fewer or no plasticity alleles...

Numerous ion channels have been shown to be regulated by the level of membrane cholesterol, but the mechanisms responsible for these effects are still not well understood. The key question in the field is how to discriminate between the contributions of the two central mechanisms that might be responsible for the sensitivity of ion channels to cholesterol: specific sterol-protein interactions or regulation of channels by the bilayer physical properties. Comparative analysis of cholesterol and its isomers on the function of an ion channel is a powerful tool to achieve this goal...

There is variation in the extent to which childhood adverse experience affects adult individual differences in maternal behavior. Genetic variation in the animal foraging gene, which encodes a cGMP-dependent protein kinase, contributes to variation in the responses of adult fruit flies, Drosophila melanogaster, to early life adversity and is also known to play a role in maternal behavior in social insects. Here we investigate genetic variation in the human foraging gene (PRKG1) as a predictor of individual differences in the effects of early adversity on maternal behavior in two cohorts...

Body image perception may impact health-promoting behaviors as well as knowledge regarding health risks associated with obesity. Our cross-sectional analysis evaluated body image and its association with body mass index among overweight and obese treatment-seeking African American women ( N = 409). Differences between current and desired body image were captured using the Pulvers scale. Results indicated the presence of body image dissatisfaction among participants (median = 2.00, interquartile range: 2...

Although infants less than 18 months old are capable of engaging in self-regulatory behavior (e.g., avoidance, withdrawal, and orienting to other aspects of their environment), the use of self-regulatory strategies at this age (as opposed to relying on caregivers) is associated with elevated behavioral and physiological distress. This study investigated infant dopamine-related genotypes (dopamine receptor D2 [DRD2], dopamine transporter solute carrier family C6, member 4 [SLC6A3], and catechol-O-methyltransferase [COMT]) as they interact with maternal self-reported history of maltreatment to predict observed infant independent emotion regulation behavior...

BACKGROUND: PCSK9 loss-of-function (LOF) variants allow for the examination of the effects of lifetime reduced low-density lipoprotein cholesterol (LDL-C) on cardiovascular events. We examined the association of PCSK9 LOF variants with LDL-C and incident coronary heart disease and stroke through a meta-analysis of data from 8 observational cohorts and 1 randomized trial of statin therapy. METHODS AND RESULTS: These 9 studies together included 17 459 blacks with 403 (2...

Oxidized modifications of LDL (oxLDL) play a key role in the development of endothelial dysfunction and atherosclerosis. However, the underlying mechanisms of oxLDL-mediated cellular behavior are not completely understood. Here, we compared the effects of two major types of oxLDL, copper-oxidized LDL (Cu(2+)-oxLDL) and lipoxygenase-oxidized LDL (LPO-oxLDL), on proliferation of human aortic endothelial cells (HAECs). Cu(2+)-oxLDL enhanced HAECs' proliferation in a dose- and degree of oxidation-dependent manner...
