Objectives: This study tests a video intervention to reduce pregnancy smoking stigma among French healthcare students.
Design: The participants were randomly selected to watch online either an experimental video (presenting educational content regarding stigma and contact with pregnant smokers) or a control video (presenting standard educational content about the risks of smoking). The students completed scales assessing stigma, intention to address smoking cessation and self-efficacy to do so, before the intervention (T0, = 252), one week after the intervention (T1, = 187), and one month after the intervention (T2, = 131).
Results: Compared to the medical students, especially men, the midwifery students reported lower derogative cognitions (ηp = .18), negative behaviours (ηp = .07) and personal distress (ηp = .06). However, the midwifery students also reported lower levels of intention to address smoking (ηp = .02) than the medical students. The experimental video decreased derogative cognitions to a greater extent than the control video (ηp = .23) in both the short and medium term. This study is the first intervention designed to reduce the stigmatisation of pregnant smokers by healthcare students. We recommend that the issue of stigma should receive more attention in the medical curriculum.

Exposure to toxins causes lasting damaging effects on the body. Numerous studies in humans and animals suggest that diet has the potential to modify the epigenome and these modifications can be inherited transgenerationally, but few studies investigate how diet can protect against negative effects of toxins. Potential evidence in the primary literature supports that caloric restriction, high-fat diets, high protein-to-carbohydrate ratios, and dietary supplementation protect against environmental toxins and strengthen these effects on their offspring's epigenome.

Nicotine is one of the most toxic substances found in cigarettes, but also found in chewing tobacco gum, patches and vaping products (electronic cigarettes). In addition to being a highly addictive chemical, it is capable of reducing fertility in men and women. In the ovaries, it can induce morphological changes and impair the formation of follicles, being a possible cause of changes in the reproductive cycle and anticipation of menopause in women whose mothers smoked during pregnancy.

Cigarette smoke (CS) has detrimental effects on placental growth and embryo development, but the underlying mechanisms remain unclear. This study aims to investigate the impact of CS on trophoblast cell proliferation and regulated cell death (RCD) by examining its interference with iron-sulfur cluster (ISC) proteins and the CIA pathway. Exposure to CS disrupted the cytosolic ISC assembly (CIA) pathway, downregulated ISC proteins, and decreased ISC maturation in the placenta of rats exposed to passive smoking.

Objectives: The associations between individual lifestyle behaviours and well-being are still poorly understood, particularly in the antenatal period when women are exposed to physiological changes and increased psychological distress. A healthy lifestyle score (HLS) comprising protective lifestyle behaviours may be useful for studying links between overall lifestyle and psychosocial outcomes. This study aimed to examine bidirectional associations between a HLS and its components and psychological well-being in pregnant women with overweight/obesity.

Background: While many pregnant women accept referrals for smoking cessation support, the uptake of telephone counselling appointments is unknown.
Aims: To determine the uptake rate of Quitline appointments among Australian pregnant women who smoke after being referred by a healthcare provider.
Materials And Methods: Data on attendance at telephone counselling appointments, number of appointments attended, gestational age at referral, referral source and smoking cessation upon completion of the program were requested from Quitline.
