    Abstract Background: Knowledge is limited on associations between social disconnectedness (i.e. loneliness and social isolation), health literacy and perceived treatment burden in individuals with cardiovascular disease (CVD). However, understanding these associations may be important for clinical practice.
    Methods: This study used cross-sectional self-reported data from the 2017 Danish health and morbidity survey entitled 'How are you?', investigating the associations of loneliness and social isolation with low health literacy and high treatment burden in individuals with CVD (n = 2521; mean age = 65.7 years).
    Results: Logistic regression analysis showed that loneliness and social isolation were associated with low health literacy in terms of difficulties in 'understanding health information' (loneliness: adjusted odds ratio (AOR) = 1.32, 95% confidence intervals (CI) [1.16, 1.50]; social isolation: AOR = 1.47, 95% CI [1.24, 1.73]) and 'engaging with healthcare providers' (loneliness: AOR = 1.53, 95% CI [1.37, 1.70]; social isolation: AOR = 1.21, 95% CI [1.06, 1.40]) and associated with high treatment burden (loneliness: AOR = 1.49, 95% CI [1.35, 1.65]; social isolation: AOR = 1.20, 95% CI [1.06, 1.37]).
    Conclusions: Our findings show that loneliness and social isolation coexisted with low health literacy and high treatment burden in individuals with CVD. These findings are critical as socially disconnected individuals experience more health issues. Low health literacy and a high treatment burden may potentially exacerbate these issues.

    Abstract Acrylamide forms in many commonly consumed foods. In animals, acrylamide causes tumors, neurotoxicity, developmental and reproductive effects. Acrylamide crosses the placenta and has been associated with restriction of intrauterine growth and certain cancers. The impact on human health is poorly understood and it is impossible to say what level of dietary exposure to acrylamide can be deemed safe as the assessment of exposure is uncertain. The determination of hemoglobin (Hb) adducts from acrylamide is increasingly being used to improve the exposure assessment of acrylamide. We aim to outline the literature on Hb adduct levels from acrylamide in humans and discuss methodological issues and research gaps. A total of 86 studies of 27,966 individuals from 19 countries were reviewed. Adduct levels were highest in occupationally exposed individuals and smokers. Levels ranged widely from 3 to 210 pmol/g Hb in non-smokers from the general population and this wide range suggests that dietary exposure to acrylamide varies largely. Non-smokers from the US and Canada had slightly higher levels as compared with non-smokers from elsewhere, but differences within studies were larger than between studies. Large studies with exposure assessment of acrylamide and related adduct forming compounds from diet during early-life are encouraged for the evaluation of health effects.

    Abstract Background: Early-life animal exposure has been associated with both protective and harmful effects on asthma and allergic disease. We aimed to explore factors that may modify associations of early-life animal exposure with asthma and allergic disease, so as to better understand these differences in findings.
    Methods: We used data from ≤84 478 children from the Danish National Birth Cohort recruited during pregnancy between 1996 and 2002, and linked registry data up to the child's 13th birthday. Adjusted Cox models were used to examine associations of early-life cat, dog, rabbit, rodent, bird and livestock exposure with atopic dermatitis, asthma and allergic rhinoconjunctivitis overall, and by source of exposure (domestic or occupation), parental history of asthma or allergy, maternal education level and timing of exposure.
    Results: Overall, associations between animal exposure and the three outcomes of interest were weak. However, dog exposure was associated with marginally lower risk of atopic dermatitis and asthma [adjusted hazard ratio (aHR) = 0.81, 95% CI: 0.70-0.94 and 0.88, 95% CI: 0.82-0.94, respectively], whereas prenatal domestic bird exposure was associated with slightly increased risk of asthma (aHR = 1.18, 95% CI: 1.05-1.32). Source of exposure, parental history of asthma or allergy and timing of exposure modified associations. Early-life animal exposure did not appear to increase the risk of allergic rhinoconjunctivitis (aHR range = 0.88, 95% CI: 0.81-0.95 to 1.00, 95% CI: 0.91-1.10).
    Conclusions: The overall weak associations observed between animal exposure and atopic dermatitis, asthma and allergic rhinoconjunctivitis were modified by type of animal, source of exposure, parental history of asthma or allergy and timing of exposure, suggesting that these factors should be considered when assessing the risks associated with early-life animal exposure.

    Abstract Background: Recent preclinical and clinical studies have shed light on the possible impact of sex and estrous/menstrual cycle on ketamine's antidepressant action but with incongruous results. The preclinical studies that have shown the effects of ovarian sex hormones have not done so in animal models of depression. Thus, the aim of the present study is to scrutinize the acute behavioral responses to a subanesthetic dose of S-ketamine in males vs females and in different estrous phases in free-cycling females in a well-powered translational approach.
    Methods: We evaluated the behavioral sensitivity to 20 mg/kg S-ketamine (i.p.) in male and female Flinders Sensitive Line rats (FSLs) and their counterpart Flinders Resistant Line rats (FRLs) subjected to the open field and forced swim tests. Female rats were disaggregated into different estrous phases, and the behavioral outcomes were compared.
    Results: Acute administration of S-ketamine had robust antidepressant-like effects in FSLs. Within our study power, we could not detect sex- or estrous cycle-specific different antidepressant-like responses to S-ketamine in FSLs. Fluctuations in the levels of ovarian sex hormones across different estrous cycles did not behaviorally affect S-ketamine's rapid-acting antidepressant mode of action. No sex-related or estrous cycle-related impact on behavioral despair was observed even among FRLs and saline-treated FSLs.
    Conclusions: We conclude that physiological oscillations of estrogen and progesterone levels neither amplify nor diminish the behavioral antidepressant-like effect of S-ketamine. In addition, fluctuations of ovarian sex hormones do not predispose female animals to exhibit enhanced or reduced depressive-like and anxiety-like behaviors.

    Abstract Introduction: Oral contraceptives (OCs) are primarily known for their effects on the reproductive system, but they can also impact the hypothalamic-pituitary-adrenal (HPA) axis. The present study aimed to compare plasma adrenocorticotropic hormone (ACTH) responses to the anticipatory stress of participating in a scientific experiment and venepuncture in OC users versus naturally cycling (NC) women, with a focus on variations throughout the menstrual cycle.
    Methods: We recruited 131 young women (average age 20.5) and obtained blood samples to measure plasma ACTH concentrations immediately after venepuncture and again after 15 min of group activities designed to facilitate interpersonal attachment and stress-buffering.
    Results: ACTH levels decreased in 70% of all participants throughout the group activities. A two-way repeated measures ANOVA highlighted a significant interaction between time and OC use, indicating differential changes in ACTH levels during social interaction between OC users and NC women. Further, the post-hoc analysis revealed that a period of stress-buffering group activities significantly decreased ACTH levels in NC women during menstrual and secretory phases, but not during the proliferative phase. In contrast, OC users did not display a decrease during group activities, regardless of the phase.
    Conclusion: This study underscores the influence of OC use on stress regulation, demonstrating that OCs not only modulate reproductive functions but also impact ACTH stress reactivity. Additionally, it emphasizes the importance of considering hormonal contraceptive use and menstrual cycle phases when assessing female stress responses.
