Objective: Transitioning to motherhood can create work family conflicts affecting mothers' health. Although employment is generally associated with longer telomeres, this may diminish during the early years of child-rearing. This study aimed to assess the impact of work reentry on telomere length (TL) among first-time mothers.

Methods: In this 1-year prospective study, a total of 103 first-time postpartum mothers participated from two medical institutions in Northern Israel; they completed validated questionnaires, reported their current working status, and provided dried blood spots measuring TL.

Results: We found that working status significantly predicted change in TL and was negatively correlated with change in TL over time (β = -0.245; 95% confidence interval, -0.169, -0.018; P = 0.016).

Conclusions: Identifying ideal timing of work reentry is recommended for first-time postpartum mother's optimal health and TL.

Objective: In a 2-group prospective design, this study compared seasonal cholinesterase levels of Latinx children in rural farmworker families and comparable urban children to assess the impact of environmental exposure to cholinesterase-inhibiting insecticides.

Methods: Quarterly blood samples and passive dosimeter wristbands were collected over 2 years in 8-year-old children (74 rural, 62 urban). Laboratory analysis assessed total cholinesterase, acetylcholinesterase, and butyrylcholinesterase from blood samples, and insecticides from wristbands.

Results: In spring and summer, total cholinesterase and acetylcholinesterase levels were depressed in rural children compared with winter and fall. Butyrylcholinesterase was depressed in rural children in fall compared with spring and summer. Adjustment for insecticide exposure did not affect these associations.

Conclusions: Environmental exposures to cholinesterase-inhibiting insecticides have measurable biochemical effects on blood cholinesterases in rural children from farmworker families.

Objective: This study examined whether mid-life work stress, defined as job strain and effort-reward imbalance (ERI), predicts work ability trajectories observed 12 years preceding the individual pensionable age. In addition, the role of sleep problems as a mediator in these associations was examined.

Methods: Survey data were collected from 2707 Finnish municipal employees.

Results: Identified work ability trajectories were "stable excellent," "stable good," "moderate," and "low decreasing." Baseline job strain and ERI were associated with a greater likelihood of belonging to impaired work ability trajectories when compared with "stable good" trajectory. Baseline sleep problems explained the association of job strain by 38% and of ERI by 54%.

Conclusions: Mid-life work stress is associated with work ability in the last years preceding pensionable age. Sleep problems might be a potential mediator in these associations.

Objectives: Purposes of this study are to study the changes in expression of vascular regulators after vibration exposure and during the onset of vibration-induced white finger (VWF) and to screen for vascular regulatory factors that could be used as early biomarkers of HAVS.

Methods: Using judgmental sampling from a Chinese factory, workers with VWF and hand-transmitted vibration exposure but without VWF were selected for research. Blood samples were taken from all subjects, and the levels of nine of the vascular regulators were measured using ELISA.

Results: Receiver operating characteristic curve analysis was performed on nine vascular regulators to assess their diagnostic sensitivity for VWF with the following area under the curve results: PGI 2 = 0.861, ANP = 0.840.

Conclusions: Collectively, PGI 2 and ANP exhibited the most potential for the early diagnosis of HAVS.

Objective: This study aimed to assess the extent to which the intensity of perceived workplace health support (PWHS) affected the incidence of psychological distress.

Methods: At the baseline, data from 4540 eligible participants throughout Japan were obtained using an Internet survey. Among them, 2362 participants who could be followed up 1 year after the initial study were included in the analysis. The intensity of PWHS was determined using an original questionnaire. Psychological distress was assessed using the Kessler Psychological Distress Scale.

Results: Participants with high PWHS were less likely to experience severe psychological distress than those with low PWHS even after adjusting for confounding factors including work-related factors. The incidence of severe psychological distress decreased as the intensity of PWHS increased.

Conclusions: Enhanced PWHS reduced psychological distress and positively affected workers' mental health.

Objective: The aim of the study is to estimate inpatient asthma hospital visit rates among impacted Texans in Public Health Region 6/5S during the year of and after Hurricane Harvey.

Methods: Asthma inpatient hospitalization discharges were collected from the Texas Health Care Information Collection database (2016-2019).

Results: Females (age-adjusted rates [AARs] = 4.8-5.0) and Black Texans (AARs = 5.0-8.1) experienced significantly higher AARs compared with males and White Texans during the year of and after Harvey. During the year of Hurricane Harvey, females were 1.49 times as likely to have an inpatient asthma visit compared with males, while Black Texans were 2.78 times as likely to have an inpatient asthma hospitalization compared with White Texans.

Conclusions: Findings from this study may assist public health professionals and local officials to allocate future resources to the most impacted subgroups as well as establish effective processes to mitigate consequences.

Objective: The aim of the study is to identify modifiable factors associated with sickness absence duration after a COVID-19 infection.

Methods: Participants in a prospective cohort of 4964 Canadian healthcare workers were asked how many working days they had missed after a positive COVID-19 test. Only completed episodes with absence ≤31 working day and no hospital admission were included. Cox regression estimated the contribution of administrative guidelines, vaccinations, work factors, personal characteristics, and symptom severity.

Results: A total of 1520 episodes of COVID-19 were reported by 1454 participants. Days off work reduced as the pandemic progressed and were fewer with increasing numbers of vaccines received. Time-off was longer with greater symptom severity and shorter where there was a provision for callback with clinical necessity.

Conclusions: Vaccination, an important modifiable factor, related to shorter sickness absence. Provision to recall workers at time of clinical need reduced absence duration.

Objective: Biomonitoring of urinary dialkyl phosphate (DAP) metabolites, a sensitive biomarker to assess pesticides exposure and also to study the impact of the use of personal protective equipment (PPE).

Methods: A preintervention-postintervention study to biomonitor dimethylphosphate, diethylphosphate, diethylthiophosphate, and diethyl-dithiophosphate using liquid chromatography with tandem mass spectrometry among Indian farmworkers (n = 120).

Results: Dimethylphosphate was detected in all samples at a mean concentration of 74.91 μg · L -1 (17.616 μg · g -1 creatinine), whereas diethylthiophosphate and diethyl-dithiophosphate were detected in 88% and 82% of samples, respectively, among farmworkers who adopted unsafe pesticide-handling practices. Intervention studies showed a significant reduction in the urinary DAP metabolites detected among the farmworkers using PPE provided to them ( P < 0.01).

Conclusions: Study confirms the exposure to pesticides among farmworkers and highlights the importance of the use of PPE to minimize exposure.
