Studies characterizing associations between phenols, phthalates and thyroid hormones during pregnancy produce inconsistent results. This divergence may be partly attributable to false positives due to multiple comparison testing of large numbers of chemicals, and measurement error as studies rely on small numbers of biospecimens despite high intra-individual variability in urinary chemical metabolite concentrations.This study employsA two-tiered approach was implemented:The ToxCast/Tox21 screening reduced the chemical set from 16 to 13 and the associated number of statistical comparisons by 19%. Parabens were negatively associated with free triiodothyronine (T3) and the T3/T4 (total thyroxine) ratio. Monobenzyl phthalate was positively associated with total T4 and negatively with the T3/T4 ratio. Effect modification by iodine status was detected for several compounds (among themFor these chemicals, screening for compounds with an increased likelihood for thyroid-related effects and relying on repeated urine samples to assess exposures improved the overall performance of multichemical analyses of thyroid disruption. This approach may improve future evaluations of human data for the thyroid pathway with implication for fetal health and may serve as a model for evaluating other toxicity outcomes. https://doi.org/10.1289/EHP10239.

International audience; Background and objectives: Studies focusing on the neurodevelopmental effects of phthalates seldom consider exposure during infancy, a critical period for brain development. Most rely on parent-completed questionnaires to assess child neurodevelopment, which may be subject to reporting error. We studied the associations between prenatal and infancy exposure to phthalates and objective measures of neurodevelopment at the age of two. Methods: We relied on 151 mother-child pairs from the SEPAGES mother-child cohort. Women were asked to collect three spot urine samples per day over seven consecutive days during the second (median: 18.0 gestational weeks) and third (median: 34.2 gestational weeks) trimesters of pregnancy. They then collected one urine sample per day over seven consecutive days from their infants around the age of 12 months. Metabolites of phthalates and non-phthalate plasticizers were measured in within-subject and within-period pools of repeated urine samples. Eye tracking tasks were performed at two years allowing to compute four indicators linked with cognitive development and visual behavior: mean fixation duration, novelty preference, percent time spent looking at the eyes and mean reaction time. Results: Pre-natal exposure to monobenzyl phthalate at the second and third trimesters was associated with shorter fixation durations. In models allowing for interaction with child sex, these associations were only observed among girls. Exposure to di(2-ethylhexyl) phthalate at the third but not the second trimester was associated with increased time spent looking at a novel face and eyes. We observed faster reaction times and decreased time spent looking at the eyes in a face recognition task, with increased post-natal exposure to monoethyl, mono-iso-butyl and mono-n-butyl phthalates. Discussion: Relying on improved exposure assessment, we highlighted associations of pre-and post-natal exposure to phthalates with indicators derived from eye tracking tasks, mainly in girls. Some of these indicators have been affected in individuals with neurodevelopmental disorders.

Contact tracing is an evidence-based intervention to control many communicable diseases, including COVID-19. Before the COVID-19 pandemic, contact tracing in Michigan focused on HIV, sexually transmitted infections, and tuberculosis, and it was conducted by state and local health department staff. Within 2 weeks of the first reported COVID-19 cases in Michigan in March 2020, the existing public health workforce was overwhelmed by the need for contact tracing and daily symptom monitoring. This case study narrates the development of a staffing plan that included volunteers and contractual staff to conduct centralized contact tracing in a home-rule state (ie, a state in which local health departments have full authority and autonomy under public health code to conduct the functions necessary to prevent disease, including contact tracing). This case study details various training, workforce management, and technology tools that were used. During the study period (May 2020–June 2021), contact tracers called 432 218 contacts and 269 439 were successfully reached, 48 134 of whom reported developing symptoms. The most important lesson learned was the need for more automated processes to improve efficiency in processing volunteer applicants, training, and scheduling. Nonetheless, the centralized workforce was successful, was flexible, and met the changing demands in Michigan.

Recent glaciations in northwestern Russia completely covered the Barents Sea during four glacial advances. At the peaks of those glacial advances, there were no nearshore macrofauna. Consequently, colonization by species that now inhabit present-day nearshore waters must have occurred since the habitat became available and hospitable, less than 15 ka. We analyzed microsatellite data from Eleginus nawaga (Gadiformes: Gadidae) collected from Khaipudyrskaya Bay in the southeastern Barents Sea with coalescent-based models to estimate the times and effective population sizes that existed before and after major historical demographic changes. Colonization of E. nawaga, which could only follow establishment of a lower trophic-level food web, provides an indicator of the for that timing. The results of the analyses were consistent with two major demographic events. After an initial founding event from a small number of individuals before ~ 140 ka, the population grew to an effective size of about 2700 individuals. Subsequently, probably as the ice receded after the Last Glacial Maximum, it plateaued at ~ 26,000 about 3000 years ago. Colonization likely came from eastern populations following the Saalian Period, after which there was little nearshore ice to the East of the Kara Sea.

This article examines how respondents understood items in the Spanish versions of the Short-Form 36 (SF-36v2). Cognitive interviews of the SF-36 were conducted in 2 phases with 46 Spanish speakers living in the United States. Roughly one-third (17/46) of respondents had difficulty understanding the Role Emotional items upon their initial reading, and almost half (21/46) provided examples that were inconsistent with the intended meaning of the items. The findings of this study underscore the importance of conducting cognitive testing to ensure conceptual equivalence of any instrument regardless of how well validated it appears to be.

Annual ice retreat in the northern Bering and Chukchi seas, which has occurred earlier in the past decades resulting in longer ice-free seasons and warmer ocean temperatures, is producing a cascade of ecological effects, and may open Arctic waters to commercial fishing and oil exploration. Baseline knowledge of population structure of a species is critical to developing strategies for management and conservation. There is little information for the saffron cod (Eleginus gracilis), an abundant forage fish inhabiting the coastlines of the North Pacific and Arctic oceans. We examined saffron cod population genetic structure with data from nine microsatellite loci designed to describe the genetic compositions of and variation among 40 collections of saffron cod from four regions (northwestern Alaska, Gulf of Alaska, western Pacific Ocean, and Gulf of Anadyr). The northwestern Alaska collections (Norton Sound and Chukchi Sea) exhibited little genetic divergence. The Gulf of Anadyr collection differed from other regions but was most similar to those of northwestern Alaska. The collections from the western Pacific Ocean (Sakhalin Island and Hokkaido Island) differed genetically, but not to the extent they did from other regions. Gulf of Alaska collections (Kodiak Island and Prince William Sound) comprised a lineage that was distinct from all of the other areas, including the geographically adjacent northwestern Alaska collections. The absence of genetic structure in northwestern Alaska probably reflects their recent expansion into previously unavailable habitat that became available after the Last Glacial Maximum (~ 16,000 years ago). Tracking and predicting the likely expansion of the eurythermal saffron cod may have parallels to its postglacial colonization.

Introduction Parents reported degraded sleep outcomes up to several years after child birth. Most published studies were cross-sectional, in early post-partum and focusing on maternal-child dyads. We aimed at identifying sleep multi-trajectories (SMT) including night (NSD) and daytime (DSD) sleep duration and subjective sleep loss (SSL) between 3 and 36 months postpartum in couples from the SEPAGES cohort. Methods From 484 mothers and 410 fathers included in the SEPAGES cohort, sleep information was collected by self-reports at 3, 18, 24 and 36 months postpartum. Couple SMT were modelled using Group-Based Trajectory Modelling method. Each couple was assigned to the group of SMT with the highest probability of belonging to. Multinomial logistic regression assessed sociodemographic, parental and child covariates associated SMT Results Three groups SMT were identified in couple who reported sleep data at least 2 times across the 4 time-points (N=188). In G1 (29.3%), couples had 8-9hr of mean NSD and a stable and relatively short mean maternal and paternal DSD (≈10min and ≈5min, respectively) while SSL was decreasing for mother (58% to 31%) but stable for father (≈30%) between 3 and 36 months postpartum. In G2 (27.7%), they had a stable but relatively short mean NSD (7-8hr), a maternal DSD decreasing by 20min between 3 and 18 months then being stable at 23min, a stable paternal DSD (≈10min) and high but decreasing SSL from 90% to 86% for mothers and 76% to 61% for fathers. In G3 (43.0%), couples had a stable mean NSD (8-9hr), a relatively long mean DSD, decreasing from 54 to 41min for mothers but increasing from 28 to 39min for fathers, and a stable but relatively high SSL (≈70% for mothers and ≈55% for fathers). From logistic regression, belated paternal chronotype increased odds for belonging to G2 while having a first child and born in autumn decreased odds to belong to G2 compared to G1. Conclusion We identified 3 different SMT between 3 and 36 months postpartum for the first time. We found several factors associated with each SMT. Studies are still warranted to investigate further interrelation with the child sleep patterns. Support (if any)

ImportanceLittle is known about long-term associations of early-life exposure to extreme temperatures with child health and lung function.ObjectivesTo investigate the association of prenatal and postnatal heat or cold exposure with newborn lung function and identify windows of susceptibility.Design, Setting, and ParticipantsThis population-based cohort study (SEPAGES) recruited pregnant women in France between July 8, 2014, and July 24, 2017. Data on temperature exposure, lung function, and covariates were available from 343 mother-child dyads. Data analysis was performed from January 1, 2021, to December 31, 2021.ExposuresMean, SD, minimum, and maximum temperatures at the mother-child’s residence, estimated using a state-of-the-art spatiotemporally resolved model.Main Outcomes and MeasuresOutcome measures were tidal breathing analysis and nitrogen multiple-breath washout test measured at 2 months of age. Adjusted associations between both long-term (35 gestational weeks and first 4 weeks after delivery) and short-term (7 days before lung function test) exposure to ambient temperature and newborn lung function were analyzed using distributed lag nonlinear models.ResultsA total of 343 mother-child pairs were included in the analyses (median [IQR] maternal age at conception, 32 [30.0-35.2] years; 183 [53%] male newborns). A total of 246 mothers and/or fathers (72%) held at least a master’s degree. Among the 160 female newborns (47%), long-term heat exposure (95th vs 50th percentile of mean temperature) was associated with decreased functional residual capacity (−39.7 mL; 95% CI, −68.6 to −10.7 mL for 24 °C vs 12 °C at gestational weeks 20-35 and weeks 0-4 after delivery) and increased respiratory rate (28.0/min; 95% CI, 4.2-51.9/min for 24 °C vs 12 °C at gestational weeks 14-35 and weeks 0-1 after delivery). Long-term cold exposure (5th vs 50th percentile of mean temperature) was associated with lower functional residual capacity (−21.9 mL; 95% CI, −42.4 to −1.3 mL for 1 °C vs 12 °C at gestational weeks 15-29), lower tidal volume (−23.8 mL; 95% CI, −43.1 to −4.4 mL for 1 °C vs 12 °C at gestational weeks 14-35 and weeks 0-4 after delivery), and increased respiratory rate (45.5/min; 95% CI, 10.1-81.0/min for 1 °C vs 12 °C at gestational weeks 6-35 and weeks 0-1 after delivery) in female newborns as well. No consistent association was observed for male newborns or short-term exposure to cold or heat.Conclusions and RelevanceIn this cohort study, long-term heat and cold exposure from the second trimester until 4 weeks after birth was associated with newborn lung volumes, especially among female newborns.

Background Ambient temperature, particularly heat, is increasingly acknowledged as a trigger for preterm delivery but study designs have been limited and results mixed. We aimed to comprehensively evaluate the association between ambient temperature throughout pregnancy and preterm delivery. Methods We estimated daily temperature throughout pregnancy using a cutting-edge spatiotemporal model for 5347 live singleton births from three prospective cohorts in France, 2002–2018. We performed Cox regression (survival analysis) with distributed lags to evaluate time-varying associations with preterm birth simultaneously controlling for exposure during the first 26 weeks and last 30 days of pregnancy. We examined weekly mean, daytime, night-time and variability of temperature, and heatwaves accounting for adaptation to location and season. Results Preterm birth risk was higher following cold (5th vs 50th percentile of mean temperature) 7–9 weeks after conception [relative risk (RR): 1.3, 95% CI: 1.0–1.6 for 2°C vs 11.6°C] and 10–4 days before delivery (RR: 1.6, 95% CI: 1.1–2.1 for 1.2°C vs 12.1°C). Night-time heat (95th vs 50th percentile of minimum temperature; 15.7°C vs 7.4°C) increased risk when exposure occurred within 5 weeks of conception (RR: 2.0, 95% CI: 1.05–3.8) or 20–26 weeks after conception (RR: 2.9, 95% CI: 1.2–6.8). Overall and daytime heat (high mean and maximum temperature) showed consistent effects. We found no clear associations with temperature variability or heatwave indicators, suggesting they may be less relevant for preterm birth. Conclusions In a temperate climate, night-time heat and chronic and acute cold exposures were associated with increased risk of preterm birth. These results suggest night-time heat as a relevant indicator. In the context of rising temperatures and more frequent weather hazards, these results should inform public health policies to reduce the growing burden of preterm births.

The first cluster of SARS-CoV-2 cases with lineage B.1.1.7 in the state of Michigan was identified through intensive university-led surveillance sampling and targeted sequencing. A collaborative investigation and response was conducted by the local and state health departments, and the campus and athletic medicine COVID-19 response teams, using S-gene target failure screening and rapid genomic sequencing to inform containment strategies. A total of 50 cases of B.1.1.7-lineage SARS-CoV-2 were identified in this outbreak, which was due to three coincident introductions of B.1.1.7-lineage SARS-CoV-2, all of which were genetically distinct from lineages which later circulated in the broader community. This investigation demonstrates the successful implementation of a genomically-informed outbreak response which can be extended to university campuses and other settings at high risk for rapid emergence of new variants.

Since the introduction of product certification in the 1980s, fair trade has grown apart from its social justice roots and the focus has steadily shifted away from calls for institutional market reform, corporate accountability, and fair prices, and toward a celebratory embrace of poverty alleviation and income growth through market integration and business partnerships. This paper examines fair trade's narratives of poverty and partnerships, focusing on the brand communication strategies employed by influential fair trade organizations and businesses. These are compared with how fair trade coffee producers in southern Mexico understand and practice partnership, demonstrating some of the ways in which the latter resist narrative framings which position them as entrepreneurial businesspeople first and cooperativistas second. The business partnerships between coffee buyers and producers are highly asymmetrical, and the partnerships that matter most for the Oaxacan coffee farmers are not with global businesses and certifiers, but instead with each other and their producer organizations. These relationships did not originate with fair trade, although, they are, in part, sustained by this system which supports democratically organized producer groups, the sharing of technical and market information, and communal management of the fair trade premium. In contrast to the organizations that certify and market their products, the paper demonstrates how farmers regard their precarious economic circumstances as an issue of social justice to be addressed through increased state support rather than market empowerment. The analytical juxtaposition of farmers' attitudes with fair trade organizational priorities contributes to the expanding literature examining how fair trade policies are experienced on the ground.

Fair trade is a trading partnership, based on dialogue, transparency, and respect, that seeks greater equity in international trade. It contributes to sustainable development by offering better trading conditions to, and securing the rights of, marginalized producers and workers. Minimum prices and social premiums linked to fair trade certifications, which require independent audit of the environmental, economic, and social conditions of commodity production and exchange, are integral to the system. Anthropological explorations of fair trade practices emphasize the cultural dimensions, socio-economic conditions, and political economy. Anthropological scholarship explores how experiences of fair trade are diversely influenced by gender; racial and ethnic identities; differences in wealth and resources, education, and geographic location; and political hierarchies and social institutions. The nuanced insights into fair trade impact produced through detailed, ethnographically driven anthropological research ultimately illustrate the limits of social movement-driven, rural-development alternatives and produce empirically informed, practical suggestions for how the current system could be improved. Anthropological expertise is appreciated within the fair trade assemblage, which encompasses development organizations, certification firms, importers, and retailers.

For non-persistent chemicals such as phthalates, a single spot urine sample only reflects exposure in the past few hours. Collecting repeated urine samples for each participant over windows of sensitivity is expected to improve exposure characterization but has rarely been done. We aimed to rely on within-subject pools of repeated urine samples to assess phthalate exposure during pregnancy and infancy. Women of the French SEPAGES mother-child cohort were asked to collect three urine samples per day over seven consecutive days, twice during their pregnancy (approximatively second (T2) and third (T3) trimesters). For their infants they also collected one sample per day during a week at two (M2) and twelve months (M12). Samples were pooled (within-subject, within-period) prior to phthalate and DINCH metabolite concentrations assessment. Number of pooled samples assayed was 477, 456, 152 and 100 for T2, T3, M2 and M12, respectively. All metabolites were detected in more than 95% of the pooled samples except for the two DINCH metabolites (oh- and oxo-MINCH), MMCHP and oh-MPHP at M2 for which detection frequencies ranged between 64% and 88%. Maternal concentrations of MiBP, MBzP, DEHP metabolites and oxo-MiNP decreased between 2014 and 2017, whereas concentrations of oh-MiNP and the two DINCH metabolites increased (Mann-Kendall p-values, Graphical abstract Image 1, Highlights • Repeated urine samples were collected and pooled within-subject, within period. • Metabolites of phthalates and DINCH were measured in pooled samples. • Frequencies of detection were overall high. • Pregnancy concentrations of MiBP, MBzP, DEHP and oxo-MINP decreased with time. • Pregnancy concentrations of oh-MiNP and DINCH metabolites increased with time., Relying on a recent cohort (2014–2017) with repeated urine samples collected during pregnancy and infancy, we showed that exposure to phthalates and DINCH is still widespread in the general population.

OBJECTIVE Patients with type 2 diabetes are encouraged to lose weight, but excessive weight loss in older adults may be a marker of poor health and subsequent mortality. We examined weight change during the postintervention period of Look AHEAD, a randomized trial comparing intensive lifestyle intervention (ILI) with diabetes support and education (DSE) (control) in overweight/obese individuals with type 2 diabetes and sought to identify predictors of excessive postintervention weight loss and its association with mortality. RESEARCH DESIGN AND METHODS These secondary analyses compared postintervention weight change (year 8 to final visit; median 16 years) in ILI and DSE in 3,999 Look AHEAD participants. Using empirically derived trajectory categories, we compared four subgroups: weight gainers (n = 307), weight stable (n = 1,561), steady losers (n = 1,731), and steep losers (n = 380), on postintervention mortality, demographic variables, and health status at randomization and year 8. RESULTS Postintervention weight change averaged −3.7 ± 9.5%, with greater weight loss in the DSE than the ILI group. The steep weight loss trajectory subgroup lost on average 17.7 ± 6.6%; 30% of steep losers died during postintervention follow-up versus 10–18% in other trajectories (P < 0001). The following variables distinguished steep losers from weight stable: baseline, older, longer diabetes duration, higher BMI, and greater multimorbidity; intervention, randomization to control group and less weight loss in years 1–8; and year 8, higher prevalence of frailty, multimorbidity, and depressive symptoms and lower use of weight control strategies. CONCLUSIONS Steep weight loss postintervention was associated with increased risk of mortality. Older individuals with longer duration of diabetes and multimorbidity should be monitored for excessive unintentional weight loss.

International audience; Background: Within-subject biospecimens pooling can theoretically reduce bias in dose-response functions from biomarker-based studies when exposure assessment suffers from classical-type error. However, collecting many urine voids each day is cumbersome. We evaluated the empirical validity of a within-subject pooling approach and compared several options to avoid sampling each void.Methods: In 16 pregnant women who collected a spot of each urine void over several nonconsecutive weeks, we compared concentrations of 10 phenols in daily, weekly, and pregnancy within-subject pools. We pooled either three or all daily samples. In a simulation study using these data, we quantified bias in dose-response functions when using one to 20 urine samples per subject to assess methylparaben (a compound with moderate within-subject variability) and bisphenol A (high variability) exposures.Results: Correlations between exposure estimates from pools of all and of only three voids per day were above 0.80 for all time windows and compounds, except for benzophenone-3 and triclosan in the daily time window (correlations, 0.57-0.68). With one spot sample to assess pregnancy exposure, correlations were all below 0.74. Using only one biospecimen led to attenuation bias in the dose-response functions of 29% (methylparaben) and 69% (bisphenol A); four samples for methylparaben and 18 for bisphenol A decreased bias to 10%.Conclusions: For nonpersistent chemicals, collecting and pooling three samples per day instead of all daily samples efficiently estimates exposures over a week or more. Collecting around 20 biospecimens can strongly limit attenuation bias for nonpersistent chemicals such as bisphenol A.

The human exposome affects child development and health later in life, but its personal external levels, variability, and correlations are largely unknown. We characterized the personal external exposome of pregnant women and children in eight European cities. Panel studies included 167 pregnant women and 183 children (aged 6-11 years). A personal exposure monitoring kit composed of smartphone, accelerometer, ultraviolet (UV) dosimeter, and two air pollution monitors were used to monitor physical activity (PA), fine particulate matter (PM2.5), black carbon, traffic-related noise, UV-B radiation, and natural outdoor environments (NOE). 77% of women performed the adult recommendation of >= 150 min/week of moderate to vigorous PA (MVPA), while only 3% of children achieved the childhood recommendation of >= 60 min/day MVPA. 11% of women and 17% of children were exposed to daily PM2.5 levels higher than recommended >= 25 mu g/m(3)). Mean exposure to noise ranged from Lden 51.1 dB in Kaunas to Lden 65.2 dB in Barcelona. 4% of women and 23% of children exceeded the recommended maximum of 2 Standard-Erythemal-Dose of UV-B at least once a week. 33% of women and 43% of children never reached the minimum NOE contact recommendation of >= 30 min/week. The variations in air and noise pollution exposure were dominated by between-city variability, while most of the variation observed for NOE contact and PA was between-participants. The correlations between all personal exposures ranged from very low to low (Rho

International audience; Introduction: Hypertensive disorders during pregnancy are one of the leading causes of maternal and offspring mortality and morbidity. Exposure to environmental chemicals is suspected to increase blood pressure (BP) but few studies have investigated the impact of non-persistent chemicals, in particular among pregnant women.Methods: Women included in the study were 152 volunteer participants in the Human Early-Life Exposome (HELIX) project. They provided 3 urine samples daily over one week in two pregnancy trimesters (at around 18 and 32 weeks of gestation) to assess their exposure to phthalates (10 metabolites), phenols (7 compounds) and organophosphate pesticides (4 metabolites). BP was measured at the end of the two collection weeks. Associations between biomarkers of exposure and BP were investigated using generalized estimating equations (GEE) and linear regression, and adjusted for potential confounders.Results: A significant decrease in systolic and/or diastolic BP was observed with exposure to some phthalate metabolites, BPA, and parabens (e.g. β GEE models for systolic BP = -0.91 mmHg (95%CI: -1.65; -0.17) per doubling of BPA concentrations). These associations were more frequently observed in the second trimester of pregnancy and remained statistically significant after correction for multiple testing for BPA only. No associations were observed with organophosphate pesticides.Conclusion: This study investigates the effect of exposure to non-persistent chemicals assessed using multiple biospecimens per subject on BP during pregnancy and suggests that higher exposure to some phthalates and phenols but not pesticides is associated with lower BP during pregnancy.

Early life stages are vulnerable to environmental hazards and present important windows of opportunity for lifelong disease prevention. This makes early life a relevant starting point for exposome studies. The Advancing Tools for Human Early Lifecourse Exposome Research and Translation (ATHLETE) project aims to develop a toolbox of exposome tools and a Europe-wide exposome cohort that will be used to systematically quantify the effects of a wide range of community- and individual-level environmental risk factors on mental, cardiometabolic, and respiratory health outcomes and associated biological pathways, longitudinally from early pregnancy through to adolescence. Exposome tool and data development include as follows: (1) a findable, accessible, interoperable, reusable (FAIR) data infrastructure for early life exposome cohort data, including 16 prospective birth cohorts in 11 European countries; (2) targeted and nontargeted approaches to measure a wide range of environmental exposures (urban, chemical, physical, behavioral, social); (3) advanced statistical and toxicological strategies to analyze complex multidimensional exposome data; (4) estimation of associations between the exposome and early organ development, health trajectories, and biological (metagenomic, metabolomic, epigenetic, aging, and stress) pathways; (5) intervention strategies to improve early life urban and chemical exposomes, co-produced with local communities; and (6) child health impacts and associated costs related to the exposome. Data, tools, and results will be assembled in an openly accessible toolbox, which will provide great opportunities for researchers, policymakers, and other stakeholders, beyond the duration of the project. ATHLETE's results will help to better understand and prevent health damage from environmental exposures and their mixtures from the earliest parts of the life course onward.
