The weak correlation between dietary and serum fatty acids suggests complex physiological regulation mechanisms. Mendelian randomization analysis establishes a protective causal link between specific plasma lipids containing ARA and gallstone disease, highlighting the genetic underpinnings of gallstone formation. This research provides a foundation for dietary interventions and underscores the importance of genetic factors in lipid metabolism for future gallstone research and clinical management. Key message What is already known on this topic?  Gallstone formation is a multifactorial process, and PUFAs may have a preventive effect, but the specific relationships between dietary fatty acids, serum fatty acids, plasma lipids, and gallstone disease are not well-established. What this study adds?  This study finds a significant association between eicosatetraenoic acid (20:4) intake and reduced gallstone risk, and establishes a protective causal link between plasma lipids containing arachidonic acid (20:4) and gallstone disease through Mendelian randomization analysis.

Rates of diagnosis of neurodivergent conditions are rising rapidly amongst patients and healthcare professionals, largely due to a recent surge in awareness and understanding of neurodiverse conditions and more inclusive diagnostic criteria. Societal adaptation, however, has lagged, and likely explains some of the psychosocial comorbidities of neurodiversity, as individuals are forced to adapt their personality and how they display their emotions to fit societal norms. There remains a lack of awareness and understanding of neurodiversity amongst the healthcare professions. There is also very limited published literature on the challenges and strengths of this group in the clinical environment. Here, we use a case study, focusing on attention deficit hyperactivity disorder to explore the relationship between neurodiversity and work from the perspective of a neurodiverse health care professional.

Multivariable MR (MVMR) and the mediation effects analysis were applied to test whether the bidirectional associations between TLs and psoriasis were mediated by body mass index (BMI), alcohol, and smoking status.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;According to the UVMR results, a negative causal impact of TL on the risk of overall psoriasis was found (OR = 0.775; 95% CI: 0.646-0.931; P = 6.36 × 10-3), and a similar trend was observed in the reversed direction for psoriasis-TL (IVW-β = -0.0097; 95% CI: -0.0170 to -0.0024; P = 9.12 × 10-3). There were also negative genetic associations between TL and PV bidirectionally. The independent association of genetically predicted TL and overall psoriasis persisted in the MVMR results controlled for BMI, smoking, and alcohol consumption (ORMVMR = 0.736; 95% CI: 0.597 to 0.907; P = 0.004). An independent significant association of genetic predisposition to PsA with TL was also found (βMVMR = 0.006; 95% CI: 0.001 to 0.012; P = 0.033). The mediation analysis showed that BMI partially mediated the reverse association between PSO and TL.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;This MR study revealed an association between genetic indicators of shortened TL and risk of overall psoriasis and PV, and genetic predisposition to PsA was associated with longer TL. Key message What is already known on this topic?  Telomere length (TL) is acknowledged to reflect an individual's biological age but is also associated with dysregulated immune function and immunosenescence. The impact of aging on psoriasis is controversial. Existing evidence suggests that aging may influence pathological changes and clinical course but whether aging is an independent risk factor remains unclear. What this study adds?  The current study found an association between genetic indicators of shortened TL and the risk of overall psoriasis and psoriasis vulgaris (PV). There was a bidirectional link between genetically indicated overall psoriasis and shortened TL. A possible positive genetic association between PsA and TL was also found. How this study might affect research, practice, or policy?  Our study may provide evidence for TL as new diagnostic and therapeutic strategies in clinical practices for psoriasis. Greater efforts to psoriasis management may substantially reduce the aging attributable to TL shortening. Future large-scale GWAS and experimental studies are warranted to examine the mechanistic basis for links between TL and psoriasis to improve under","PeriodicalId":20374,"journal":{"name":"Postgraduate Medical Journal","volume":" ","pages":"147-155"},"PeriodicalIF":3.6,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142140861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
