Prenatal phthalate exposure and performance on the Neonatal Behavioral Assessment Scale in a multiethnic birth cohort
We investigated the relationship between prenatal maternal urinary concentrations of phthalate metabolites and neonatal behavior in their 295 children enrolled in a multiethnic birth cohort between 1998 and 2002 at the Mount Sinai School of Medicine in New York City. Trained examiners administered the Brazelton Neonatal Behavioral Assessment Scale (BNBAS) to children within 5 days of delivery. We measured metabolites of 7 phthalate esters in maternal urine that was collected between 25 and 40 weeks' gestation. All but two phthalate metabolites were over 95% detectable. We summed metabolites on a molar basis into low and high molecular weight phthalates. We hypothesized the existence of sex-specific effects from phthalate exposure a priori given the hormonal activity of these chemicals. Overall we found few associations between individual phthalate metabolites or their molar sums and most of the BNBAS domains. However, we observed significant sex-phthalate metabolite interactions (p < 0.10) for the Orientation and Motor domains and the overall Quality of Alertness score. Among girls, there was a significant linear decline in adjusted mean Orientation score with increasing urinary concentrations of high molecular weight phthalate metabolites (B = -0.37, p = 0.02). Likewise, there was a strong linear decline in their adjusted mean Quality of Alertness score (B = -0.48, p < 0.01). In addition, boys and girls demonstrated opposite patterns of association between low and high molecular weight phthalate metabolite concentrations and motor performance, with some indication of improved motor performance with increasing concentration of low molecular weight phthalate metabolites among boys. This is the first study to report an association between prenatal phthalate exposure and neurological effects in humans or animals, and as such requires replication
Whole-genome sequencing reveals host factors underlying critical COVID-19
Critical COVID-19 is caused by immune-mediated inflammatory lung injury. Host genetic variation influences the development of illness requiring critical care1 or hospitalization2,3,4 after infection with SARS-CoV-2. The GenOMICC (Genetics of Mortality in Critical Care) study enables the comparison of genomes from individuals who are critically ill with those of population controls to find underlying disease mechanisms. Here we use whole-genome sequencing in 7,491 critically ill individuals compared with 48,400 controls to discover and replicate 23 independent variants that significantly predispose to critical COVID-19. We identify 16 new independent associations, including variants within genes that are involved in interferon signalling (IL10RB and PLSCR1), leucocyte differentiation (BCL11A) and blood-type antigen secretor status (FUT2). Using transcriptome-wide association and colocalization to infer the effect of gene expression on disease severity, we find evidence that implicates multiple genes—including reduced expression of a membrane flippase (ATP11A), and increased expression of a mucin (MUC1)—in critical disease. Mendelian randomization provides evidence in support of causal roles for myeloid cell adhesion molecules (SELE, ICAM5 and CD209) and the coagulation factor F8, all of which are potentially druggable targets. Our results are broadly consistent with a multi-component model of COVID-19 pathophysiology, in which at least two distinct mechanisms can predispose to life-threatening disease: failure to control viral replication; or an enhanced tendency towards pulmonary inflammation and intravascular coagulation. We show that comparison between cases of critical illness and population controls is highly efficient for the detection of therapeutically relevant mechanisms of disease
Lack of effect of psychosocial stress on maternal corticotropin-releasing factor and catecholamine levels at 28 weeks' gestation
OBJECTIVE: Corticotropin-releasing factor (CRF) and catecholamines are among the major hormones
activated during the adaptive response to stressful stimuli. In pregnant women, serum CRF and catecholamines
levels increase during labor and preterm delivery. The aim of the present study was to evaluate
whether psychosocial stress measures are correlated with serum CRF or urinary catecholamine [ie, epinephrine,
norepinephrine (NE), dopamine (DA)] levels in healthy midtrimester pregnant women.
METHODS: A large group of white pregnant women (n 5 382) participated in the present study. The
Work Conditions Questionnaire and the Psychiatric Epidemiology Research Interview were administered to
measure job stress and general life stress, respectively. Urine and blood specimens were collected at 28 weeks
of gestation at the time of psychosocial evaluation. Epinephrine, NE, and DA were quantified in the urine
by a highly sensitive method based on an amperometric detector. Serum CRF and cortisol levels were
measured in blood specimens by using specific radioimmunoassays.
RESULTS: Serum CRF and cortisol levels did not vary between patients with high and low scores on
psychological tests, and no correlation was found between CRF and cortisol levels. One job stress measure,
low job latitude, was significantly associated with a mild increase in NE and DA levels in the afternoon and
night (P , .05, analysis of variance). Serum cortisol levels were inversely correlated with NE in the morning
(r520.447; P 5 .002) and night segments (r520.391; P 5 .007) and with DA in the night period
(r 5 20.367; P 5 .013).
CONCLUSION: The absence of a significant relationship between CRF/cortisol and psychosocial stress
measures in pregnant women suggests that the hypothalamic–pituitary–adrenal response to psychosocial stress
may be masked at midtrimester by the constantly high levels of placental CRF, whose control is beyond the
influence of environmental stressors
Senior oral health: A community-based, interprofessional educational experience for nursing and dental students
The current article highlights an interprofessional, older adult oral health community program, created through an Accelerating Interprofessional Community-Based Education and Practice grant from the National Center for Interprofessional Practice and Education, designed to address the gap between older adult health education and care delivery. This project developed an advanced practice, nurse-led partnership among The Hartford Institute for Geriatric Nursing and the Oral Health Nursing Education and Practice Program (both located at New York University Rory Meyers College of Nursing), New York University College of Dentistry, and Regional Aid for Interim Needs (RAIN), a community service organization for older adults in the Bronx. Teams of nursing (n = 26), nurse practitioner (n = 16), and dental (n = 64) students provided oral health education and oral hygiene instruction using Tooth Wisdom® educational materials to older adults, home health aides (HHAs), and volunteers in nine RAIN senior centers. Students demonstrated increases in their self-reported interprofessional competencies based on the Interprofessional Collaborative Competency Attainment Survey. Results also revealed that older adults (n = 500), HHAs (n = 142), and volunteers (n = 21) at the RAIN senior centers who attended the Tooth Wisdom presentation demonstrated an increase in oral health knowledge
