- Epidemiological studies suggest that exposure to persistent organic pollutants such as organochlorines might induce cardiovascular disorders and diabetes. Some of these organochlorines, such as dioxins and some dioxin-like PCBs, have been characterised as anti-estrogenic due to their inhibition of estrogenic-induced responses. In the present pilot study, 40 female rats were subjected to either exposure to the dioxin-like 3,3',4,4',5-pentachlorobiphenyl (PCB 126) or vehicle, as well as ovariectomy (OVX) or sham operation in a 2 x 2 factorial design over 12 weeks to explore potential interactions between estrogen status and PCB 126 exposure on cardiovascular risk factors. PCB 126 increased heart weight and serum cholesterol levels in both groups. PCB 126 increased blood pressure in the sham-operated animals only. In conclusion, PCB 126 exposure in female rats resulted in effects on cardiovascular risk factors, such as serum cholesterol, blood pressure, and heart weight. Of these effects of PCB 126, the increase in blood pressure was dependent on estrogen status.

- Background: Dietary change towards a diet low in greenhouse gas emissions (GHGEs) can reduce climate impact and improve individual-level health. However, there is a lack of understanding if diet interventions can achieve low-GHGE diets.Methods: A randomized controlled trial was conducted to assess the effects of an app-based intervention. The intervention was designed to improve dietary intake of people with Type 2 diabetes, and was delivered via an app over 12 weeks, with each week covering one diet-related topic. Dietary intake was assessed at baseline and 3-month follow up by a 95-item food frequency questionnaire and linked to GHGE values. A total of n = 93 participants (n = 46 and n = 47 for the intervention and control group, respectively) were included in the analysis. Changes to GHGEs within and between the groups were analysed with inferential statistics.Results: The majority (60%) of participants were male, with a mean age of 63.2 years and body mass index of 30 kg/m2. At baseline, diet-related GHGEs were 4.8 and 4.9 kg CO2-eq/day in the intervention and control group, respectively. At 3-month follow up the corresponding GHGEs were 4.7 and 4.9 kg CO2-eq/day. We found no statistically significant changes to diet-related GHGEs within or between groups, or within food categories, from baseline to 3-month follow up.Conclusion: No evidence was found for the effectiveness of the app-based intervention to generate changes to diet-related GHGEs in a population of people with Type 2 diabetes. However, future interventions that target reducing meat consumption specifically may have the potential to result in a reduction of individual-level diet-related GHGEs.Trial registration ClinicalTrials.gov, NCT03784612.

- Introduction: Little is known about factors that influence patients' choice to use physical or digital primary care. This study aimed to compare self-rated health, internet habits, and what patients deem important when choosing health care between users of physical and digital primary health care. Methods: We recruited 2,716 adults visiting one of six physical or four digital primary health care providers in Stockholm, Sweden, October 2020 to May 2021. Participants answered a questionnaire with questions about sociodemography, self-rated health, internet habits, and what they considered important when seeking care. We used logistic regression and estimated odds ratios (ORs) for choosing digital care. Results: Digital users considered themselves healthier and used the internet more, compared with physical users (p < 0.001). Competence of health care staff was the most important factor when seeking care to both physical and digital users (90% and 78%, respectively). Patients considering it important to avoid leaving home were more likely to seek digital care (OR 29.55, 95% confidence interval [CI] 12.65?69.06), while patients valuing continuity were more likely to seek physical care (OR 0.25, 95% CI 0.19?0.32). These factors were significant also when adjusting for self-rated health and sociodemographic characteristics. Conclusion: What patients considered important when seeking health care was associated with what type of care they sought. Patient preferences should be considered when planning health care to optimize resource allocation.
