The developmental mental-disorder histories of adults with posttraumatic stress disorder: A prospective longitudinal birth cohort study.

BACKGROUND Prenatal exposure to pesticides have been linked to adverse neurodevelopmental outcomes. Gaps exist in the current literature about the timing and magnitude of exposures that result in these adverse outcomes. OBJECTIVE The Study of Asian Women and their Offspring’s Development and Environmental Exposures (SAWASDEE) Cohort was established to investigate the impact of prenatal exposure to pesticides on neurodevelopment during infancy and early childhood in northern Thailand. METHODS Recruitment of this prospective, longitudinal birth cohort began in July 2017 and was completed in June 2019 in Chom Thong and Fang, two farming districts in Chiang Mai Province in northern Thailand. Follow up of the study participants is on-going. During pregnancy, seven questionnaires were administered. Time-resolved biospecimen samples were collected monthly (for urine) and during each trimester (for blood) at antenatal care visits. Medical records were abstracted. Infants were administered the NICU Network Neurobehavioral Scale (NNNS) test at one month of age. We will complete a number of additional exposure related analyses. RESULTS A total of 1298 women were screened and of those 394 women were enrolled. The mean gestational age at enrollment was 9.9 weeks (STD = 2.6). Differences in literacy were observed between Chom Thong and Fang participants. In Fang about 51% reported being able to read in Thai compared to about 95% in Chom Thong. The percentages were comparable for reporting to be able to write in Thai. A total of 322 mother-child pairs completed the NNNS. CONCLUSIONS This longitudinal birth cohort study will inform risk assessment standards for pregnant women in Thailand and other countries. Building awareness of how insecticide exposure during specific windows of pregnancy affects the neurodevelopmental trajectories of children in developing countries is a specific need recognized by the World Health Organization.

Purpose. This study aimed to measure symptoms of posttraumatic stress disorder (PTSD) in Chinese patients following a new diagnosis of lung cancer. Secondary aims were to explore factors at diagnosis that may predict PTSD symptoms at 6 months. Methods. This was a prospective longitudinal observational study that included 93 patients with newly diagnosed lung cancer. PTSD symptomology was assessed using the PTSD Checklist Civilian Version (PCL-C) and health-related quality of life (HRQoL) was assessed with the European Organisation for the Research and Treatment of Cancer questionnaire. Measures were completed at diagnosis and 6 months. Results. No patient had PTSD at baseline or 6 months as measured by a score of ⩾50 in the PCL-C. However, at diagnosis, 44% of patients had “mild” symptoms of PTSD. At 6 months, 64% of patients had “mild” and 8% had “moderate” PTSD symptoms. PTSD symptom scores significantly worsened over 6 months (mean difference [95% CI] = 7.2 [5.4 to 9.0]). Six months after diagnosis, higher PTSD scores were seen in people who at diagnosis were younger ( P = .003), had a lower smoking pack history ( P = .012), displayed less sedentary behavior ( P < .005), or initially had worse cancer symptoms, including fatigue ( P = .001) and poorer HRQoL ( P = .004). Conclusions. Mild PTSD symptoms are common in patients with lung cancer 6 months after treatment; however, a full diagnosis of PTSD is uncommon. Screening for PTSD symptoms may be considered for at-risk patients with newly diagnosed lung cancer.
