Association of exposure to ozone and fine particulate matter with ovarian reserve among women with infertility
https://pubmed.ncbi.nlm.nih.gov/37926414/

-- Further analyses indicated that the reduced ovarian reserve measured by AMH level was only significantly associated with PM2.5 exposure during follicle development from the primary to preantral follicle stage (Period 2) but was significantly associated with O3 exposure during Periods 1, 2, and 3. These observations were robust in the dual-pollutant model considering co-exposure to PM2.5 and O3. The results indicated an inverse association between ovarian reserve and ambient O3 exposure and suggested distinct susceptibility windows for O3 and PM2.5 for reduced ovarian reserve. These findings highlight the need to control ambient air pollution to reduce invisible risks to women's fertility, especially at high O3 concentrations.

Influence of Mild Chronic Stress and Social Isolation on Acute Ozone-Induced Alterations in Stress Biomarkers and Brain-Region-Specific Gene Expression in Male Wistar-Kyoto Rats
https://pubmed.ncbi.nlm.nih.gov/38001817/

Individuals with psychosocial stress often experience an exaggerated response to air pollutants. Ozone (O3) exposure has been associated with the activation of the neuroendocrine stress-response system. We hypothesized that preexistent mild chronic stress plus social isolation (CS), or social isolation (SI) alone, would exacerbate the acute effects of O3 exposure on the circulating adrenal-derived stress hormones, and the expression of the genes regulating glucocorticoid stress signaling .....

Short-term exposure to ozone may trigger the onset of Kawasaki disease: An individual-level, case-crossover study in East China
https://pubmed.ncbi.nlm.nih.gov/38040257/

Abstract

Kawasaki disease (KD) is an acute, systemic vasculitis that primarily affects children aged under the age of 5. While environmental factors have been linked to the development of KD, the specific role of ozone (O3) pollution in triggering the disease onset remains uncertain. This study aimed to examine the associations between short-term O3 exposure and KD onset in children. ....Our findings revealed a significant association of O3 exposure with KD onset on the day of onset(lag 0 day) ...

Kawasaki disease, autoimmune disorders, and cancer: a register-based study https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7415012/

...Studies indicate that KD is triggered by an abnormal autoimmune response caused by an infection [7–9], but no definitive agent has been found. The potent anti-inflammatory effect of immunoglobulin treatment in the early stages of the disease indicates that autoimmunity or auto-inflammation could be essential in KD [10, 11], which one of these factors that are the most important has not been clarified [10]. However, this observation could suggest that KD might be a severe autoimmune manifestation in a child predisposed to other autoimmune diseases later in life. Yet, no long-term follow-up studies have yet investigated this theory.

Conclusion:
Exposure to increased levels of ozone but not particulate air pollution was associated with higher risk of mortality in patients with sepsis. This association was strongest in patients with pneumonia but persisted in all sources of sepsis. Further work is needed to understand the relationship between ambient ozone air pollution and sepsis

Conclusions

This study suggests that MS is associated with an increased risk of cardiovascular and cerebrovascular disease that is not completely accounted for by traditional vascular risk factors. Given the adverse effects of these comorbidities on outcomes in patients with MS, further investigation is needed.

Molecular Regulation of the CNS by Vitamin D
https://pubmed.ncbi.nlm.nih.gov/38116771/


Abstract

Vitamin D is a lipid-soluble vitamin that can be found in some foods. It is also produced endogenously (in the presence of ultraviolet light), transported through the blood to the targets organs and this is the reason to consider vitamin D as a hormone. It is known that vitamin D has genomic and non-genomic effects. This review is focused mainly on the vitamin D receptors, the importance of vitamin D as a neuromodulator, the role of vitamin D in the pathophysiology of devastating neurological disorders such as Alzheimer's disease, multiple sclerosis, amyotrophic lateral sclerosis, Parkinson's disease and the benefit of vitamin D and its derivates in alleviating these disorders.

Myocardial infarction and stroke risks in multiple sclerosis patients: A two-sample Mendelian randomization study
https://pubmed.ncbi.nlm.nih.gov/35066269/

Abstract
Observational studies indicated multiple sclerosis (MS) patients may have a higher risk of myocardial infarction (MI) and stroke than the general population, whereas the previously reported findings were inconsistent. Using two-sample Mendelian randomization (MR) analysis with genetic data from large-scale genome-wide association studies (International Multiple Sclerosis Genetics Consortium containing 14,498 MS cases, Coronary ARtery DIsease Genome wide Replication and Meta-analysis plus The Coronary Artery Disease Genetics consortium containing 43,676 MI cases and 40,585 stroke cases), we found that MS was causally associated with an increased risk of MI (OR = 1.03; 95%CI 1.00-1.06; P = 0.0243), directionally consistent in the weighted median, MR-Egger, and the MR-PRESSO methods. No causal association between MS and stroke was observed (OR = 1.01; 95%CI 0.99-1.04; P = 0.2974). Therefore, timelier and more effective measures should be conducted among MS patients to decrease the burden of both diseases.

Association of multiple sclerosis with stroke: A comprehensive review
https://pubmed.ncbi.nlm.nih.gov/38264155/

Conclusion: In conclusion, this review underscores the critical need for a thorough understanding of the complex relationship between MS and stroke. The identified risk factors and the influence of MS DMTs on stroke risk necessitate further investigation to inform evidence-based preventive and therapeutic strategies. Bridging the existing information gaps through prospective multicenter studies is imperative for a comprehensive understanding of this association. The development of targeted diagnostic and therapeutic approaches for acute stroke risk in MS patients is paramount to mitigate the impact of these debilitating conditions. Ultimately, this review serves as a foundation for future efforts to enhance preventative measures and therapeutic interventions, thereby improving the overall quality of life for individuals with MS susceptible to strokes.

Effect of ozone exposure on the foraging behaviour of Bombus terrestris
https://pubmed.ncbi.nlm.nih.gov/36334775/

Abstract

Tropospheric ozone (O3) mixing ratios have increased substantially since preindustrial times and high O3 peaks are increasingly common. Plant-pollinator interactions are central to natural ecosystem functioning and food production systems but could be negatively affected by unfavourable environmental conditions such as elevated O3. Ecosystem functioning is threatened by O3, which can degrade floral volatile organic compounds (VOCs) used by pollinators as olfactory cues during foraging. It can also exert oxidative stress on VOC-emitting plants and receiving organisms, potentially disturbing the sending and receiving of VOC signals....
