A screening questionnaire for occupational and hobby exposures during pregnancy.

ABSTRACT: BACKGROUND:Occupational and environmental exposures during the prenatal period may be associated with adverse pregnancy outcomes and lifelong health effects. Yet, identification and evaluation of these potential hazards is lacking in routine obstetric care. AIMS:To assess the feasibility of incorporating a self-administered occupational and environmental exposure questionnaire into obstetric clinics. METHODS:A cross-sectional survey assessed prenatal clinic patients at a public hospital who were currently employed and <20 weeks gestation. Questionnaires evaluated job characteristics, workplace and hobby exposures, protective equipment use and symptoms during pregnancy. RESULTS:Of 69 participants (96% response rate), 46% were predominantly Spanish-speaking. Primary occupations were caregiver (16%), cleaner (14%) and administrative assistant (14%). Overall, 93% were exposed to a workplace hazard, with most participants reporting physical stressors (82%) or organic solvent exposure (78%). Most women (74%) used some personal protective equipment. Nearly half (54%) reported at least one non-pregnancy symptom, and 52% were referred for follow-up with an occupational medicine practitioner. Household and hobby-related chemical exposures were common in our sample (91%). We observed moderate consistency between job task and chemical use responses: 67-99% of intentionally redundant questions were fully or partially matched. Closed- compared to open-ended activity questions identified a higher proportion of physical stressors (82% versus 12%) and cleaning product (76% versus 30%) exposures. CONCLUSIONS:A self-administered questionnaire is an effective screening tool for identifying women with occupational and hobby-related exposures during pregnancy. Consistent incorporation of exposure assessment into prenatal care can improve clinical communications and early interventions for at-risk pregnant women.

Project description:Silicone wristbands can assess multipollutant exposures in a non-invasive and minimally burdensome manner, which may be suitable for use among pregnant women. We investigated silicone wristbands as passive environmental samplers in the New Hampshire Birth Cohort Study, a prospective pregnancy cohort. We used wristbands to assess exposure to a broad range of organic chemicals, identified multipollutant exposure profiles using self-organizing maps (SOMs), and assessed temporal consistency and determinants of exposures during pregnancy. Participants (n = 255) wore wristbands for 1 week at 12 gestational weeks. Of 1,530 chemicals assayed, 199 were detected in at least one wristband and 16 were detected in >60% of wristbands. A median of 23 (range: 12,37) chemicals were detected in each wristband, and chemicals in commerce and personal care products were most frequently detected. A subset of participants (n=20) wore a second wristband at 24 gestational weeks, and concentrations of frequently detected chemicals were moderately correlated between time points (median intraclass correlation: 0.22; range: 0.00,0.69). Women with higher educational attainment had fewer chemicals detected in their wristbands and the total number of chemicals detected varied seasonally. Triphenyl phosphate concentrations were positively associated with nail polish use, and benzophenone concentrations were highest in summer. No clear associations were observed with other a priori relations, including certain behaviors, season, and socioeconomic factors. SOM analyses revealed 12 profiles, ranging from 2 to 149 participants, captured multipollutant exposure profiles observed in this cohort. The most common profile (n = 149) indicated that 58% of participants experienced relatively low exposures to frequently detected chemicals. Less common (n ≥ 10) and rare (n < 10) profiles were characterized by low to moderate exposures to most chemicals and very high and/or very low exposure to a subset of chemicals. Certain covariates varied across SOM profile membership; for example, relative to women in the most common profile who had low exposures to most chemicals, women in the profile with elevated exposure to galaxolide and benzyl benzoate were younger, more likely to be single, and more likely to report nail polish use. Our study illustrates the utility of silicone wristbands for measurement of multipollutant exposures in sensitive populations, including pregnant women.

Project description:Background and objectivesMembranous nephropathy is a rare autoimmune kidney disease whose increasing prevalence in industrialized countries pleads for the involvement of an environmental factor in the development of the disease. In addition, the predominance of men in membranous nephropathy, classically attributed to biologic or genetic differences between men and women, could also be due to different occupational exposures. To support this hypothesis, we sought to describe the toxic occupational exposures of patients with membranous nephropathy.Design, setting, participants, & measurementsIn this observational epidemiologic study, we compared the occupations and toxic occupational exposures of 100 patients with membranous nephropathy with those of the general population, consisting of two cohorts of 26,734,000 and 26,500 French workers. We then compared the characteristics of patients exposed to an occupational toxic substance with those of unexposed patients.ResultsPatients with membranous nephropathy worked more frequently in the construction sector than the general population (33% versus 7%, P<0.001). This difference remained significant by age and sex. They were also more frequently exposed to toxic substances, such as asbestos (16% versus 5%, P<0.001), lead (9% versus 1%, P<0.001), or organic solvents (37% versus 15%, P<0.001), than the general population. The predominance of men in the subgroup of patients occupationally exposed to toxic substances was not observed in unexposed individuals (organic solvents: 80% men versus 41%, P<0.001; asbestos: 90% men versus 55%, P=0.004). In addition, patients with phospholipase A2 receptor 1 (PLA2R1) epitope spreading were more frequently exposed to asbestos and organic solvents than patients without epitope spreading (32% versus 7%, P=0.02 and 74% versus 43%, P=0.02, respectively), with a dose-dependent effect.ConclusionsPatients with membranous nephropathy were more frequently exposed to certain occupational toxic substances, such as asbestos and organic solvents, than the general population. This occupational exposure was more frequent in men and in patients with PLA2R1 epitope spreading.Clinical trial registry name and registration numberImmunopathological Analysis in a French National Cohort of Membranous Nephropathy (IHMN), NCT04326218.PodcastThis article contains a podcast at https://www.asn-online.org/media/podcast/CJASN/2022_10_25_CJN02930322.mp3.

Project description:BackgroundVariation exists regarding perinatal depression screening. A two-step screening method has been recommended. According to a maternity-focused core outcome set developed by the International Consortium for Health Outcomes Measurement, women who score 3 or more on the PHQ-2 then complete the Edinburgh Postnatal Depression Scale (EPDS). Limited evidence exists regarding the screening accuracy of the PHQ-2 in childbearing women. An alternative case-identification method may be more sensitive for perinatal women. We aimed to [1] evaluate the screening accuracy of the PHQ-2 during the perinatal period using two case-identification methods, and [2] measure the variability of accuracy over four time-points during pregnancy and postpartum.MethodsA prospective, longitudinal cohort study was conducted with 309 consecutive women who completed the PHQ-2 and EPDS during pregnancy (booking, 36-weeks) and postpartum (6-, 26-weeks). EPDS was the reference standard using cut-off scores for 'at least probable minor depression' during pregnancy (??13) and postpartum (??10) and for 'probable major depression' during pregnancy (??15) and postpartum (??13). PHQ-2 was analysed using two methods: [1] scored (cut-points ? 2 and ? 3), [2] dichotomous yes/no (positive response to either question) against EPDS cut-points for at least probable minor and probable major depression. Receiver operating characteristic analyses determined accuracy.ResultsProbable major depression: Over four timepoints PHQ-2 ? 3 revealed lowest sensitivity (36-79%) but highest specificity (94-98%). An alternative case-identification method revealed high sensitivity (93-100%), but lowest specificity (58-71%). Minor depression: PHQ-2 ? 3 revealed the lowest sensitivity (19-50%) but highest specificity (95-98%). An alternative case-identification method revealed the highest sensitivity (81-100%) and moderate specificity (60-74%).ConclusionsRecommended method of case-identification (PHQ-2 ? 3) missed an unacceptable number of women at-risk of depression. As a clinical decision-making tool, an alternative, dichotomous method maximized case-identification and is recommended. Further, the literature identified inconsistent reporting of the PHQ-2 and the alternative case-identification method hindering the ability to synthesise data. The future use and reporting of consistent question wording and response format will improve outcome reporting and synthesis. Further research in larger and diverse maternity populations is recommended.

Project description:BackgroundSleep Disorder Breathing (SDB) in pregnant patients ranges from 3 to 27% and varies depending on gestational age and method used to diagnose. SDB increases the risk of advanced pregnancy complications such as gestational diabetes mellitus, pregnancy-induced hypertension, and preeclampsia. Screening and diagnosis of SDB during pregnancy remains a challenge, with existing screening tools underperforming during pregnancy. This study aimed to validate a previously developed model for predicting SDB during late pregnancy and compare the predictive value of bedpartner responses.MethodsNinety-six women in the third trimester of pregnancy underwent polysomnography and completed the Berlin Questionnaire (BQ), with 81 bedpartners completing the BQ about their pregnant partner. A subset of BQ items (snoring volume and tiredness upon awakening) along with BMI > 32 kg/m2 was utilised to calculate the Wilson Optimized Model (WOM), which demonstrated strong predictive properties in development.ResultsSDB (RDI/hr ≥ 5) was detected in 43.8% of women. BQ identified 72% of pregnant mothers as high risk for SDB (Sensitivity = 83%, Specificity = 37%), compared to 29% of mothers identified by the WOM (Sensitivity = 45%, Specificity = 83%). At RDI of ≥ 15, the WOM correctly classified more women according to SDB risk than the BQ (76.0% vs. 41.7% cases correct, X2(1) = 23.42, p < .001), with no difference at RDI ≥ 5. Bedpartners were more likely to report high risk for SDB on the WOM than pregnant women themselves (38.3% vs. 28.4%), however predictive ability was not improved by bedpartner input (RDI ≥ 5 bedpartner AUC = 0.69 v mother AUC = 0.73).ConclusionBQ largely overestimates the prevalence of SDB in pregnancy compared to the WOM which underestimates. Utilising bedpartner responses didn't improve screening for SDB in late pregnancy. More work is needed to develop a pregnancy-specific tool for quick and accurate screening for SDB.
