"I Pumped That Milk Off My Breast and Dumped It in Trash": Breastfeeding Experiences of Mothers Working in hospital radiation settings-A Qualitative Study

Purpose: The qualitative study was conducted to determine the breastfeeding experiences of mothers working in radiation areas in hospitals. Materials and Methods: The study was conducted in Turkey between December 2022 and February 2023 through in-depth interviews held with 13 mothers who met the inclusion criteria. The content analysis method was used in the analysis of the data. Results: As a result of the analyses of the data obtained in the interviews, four themes regarding the breastfeeding experiences of health professionals working in radiation environments in hospitals were identified. These themes were institutional/administrative obstacles, support systems, unhealthy childcare, and feeling of incompetence as a mother. The main theme of unhealthy childcare consisted of four categories, which were low-quality breast milk, toxic breast milk, frequent diseases, and future risk of cancer. The main theme of feeling of incompetence as a mother was composed of three categories, which were fear, feeling of guilt, and "Am I a mother?" The theme of institutional/administrative obstacles consisted of three categories, namely working environment, working duration, and awareness of managers. Finally, the theme of support systems included two categories, positive perceptions and negative perceptions. Conclusion: In this study, it was determined that the mothers who worked in radiation areas in hospitals experienced problems due to individual, social, and institutional factors. The main concern of the mothers was found to be hurting their infants with their breast milk. Suitable working environments and the adequacy of practices related to daycare centers, social support, and motherhood rights are the main needs of working mothers aiming to keep breastfeeding their infants.

What to Expect When Expecting in Lab: A Review of Unique Risks and Resources for Pregnant Researchers in the Chemical Laboratory

Pregnancy presents a unique risk to chemical researchers due to their occupational exposures to chemical, equipment, and physical hazards in chemical research laboratories across science, engineering, and technology disciplines. Understanding “risk” as a function of hazard, exposure, and vulnerability, this review aims to critically examine the state of the science for the risks and associated recommendations (or lack thereof) for pregnant researchers in chemical laboratories (labs). Commonly encountered hazards for pregnant lab workers include chemical hazards (organic solvents, heavy metals, engineered nanomaterials, and endocrine disruptors), radiation hazards (ionizing radiation producing equipment and materials and nonionizing radiation producing equipment), and other hazards related to the lab environment (excessive noise, excessive heat, psychosocial stress, strenuous physical work, and/or abnormal working hours). Lab relevant doses and routes of exposure in the chemical lab environment along with literature and governmental recommendations or resources for exposure mitigation are critically assessed. The specific windows of vulnerability based on stage of pregnancy are described for each hazard, if available. Finally, policy gaps for further scientific research are detailed to enhance future guidance to protect pregnant lab workers.

Treatment of adult Graves' disease

Treatment strategy in Graves' disease firstly requires recovery of euthyroid status by antithyroid therapy. Treatment modalities, precautions, advantages and side-effects are to be discussed with the patient. No particular treatment modality has demonstrated superiority. Pregnancy or pregnancy project affects choice of treatment and monitoring. Graves' orbitopathy is liable to be aggravated by iodine-131 treatment and requires pre-treatment assessment. Iodine-131 treatment aims at achieving hypothyroidism. Thyroid surgery for Graves' disease should preferably be performed by an expert team. In case of recurrence of hyperthyroidism, the various treatment options should be discussed with the patient. Empiric treatment of thyroid dermopathy uses local corticosteroids in occlusive dressing.
